Last year, we tracked the budding relationships of several celebrities  that were coupling up and showing PDA around the world. Many of the flings fizzled, but other pairs — like Amanda Seyfried  and Justin Long , Amy Poehler  and Nick Kroll, and Jake Gyllenhaal  and Alyssa Miller — are still going strong. Donnie Wahlberg and Jenny McCarthy 's Summer love resulted in a wedding , and Zoe Saldana is expecting twins  with her Spring fling (and now-husband), Marco Perego!
Cut to 2014, and there were plenty more new couples going public with their love. Khloé Kardashian found — then lost — a new boyfriend in rapper French Montana, while Joseph Gordon-Levitt is currently getting cozy with Tasha McCauley , the cofounder and CEO of a robotics company based in Silicon Valley. There's also Joe Manganiello and Sofia Vergara, who have been spotted all over each other from coast to coast, and Jennifer Lawrence and Chris Martin , who kept their A-list love under wraps before splitting up. Scroll through to see how these celebrity couples have held up this year , and vote for your favorite new duo of 2014 !
Ian Somerhalder and Nikki Reed
Ian Somerhalder  and Nikki Reed  were spotted getting quite cozy  during a farmers market trip together in mid-July. Ian was all over Nikki as she checked out produce, slinging his arm around her shoulder and planting kisses on her head. The following month, they packed on the PDA  backstage at the Teen Choice Awards.
These two have a history of hooking up within the same Hollywood circle; Ian dated Nikki's Twilight costar Ashley Greene  briefly back in 2009, and Nikki's close friend, Nina Dobrev , called it quits with Ian in May 2013 after a three-year relationship. If that wasn't weird enough, Nina and Nikki were both linked to Dancing With the Stars hunk Derek Hough after their respective breakups (Nikki announced her split from husband Paul McDonald in March). Despite their close-knit friend group, Nikki and Ian seem to be going the distance — Ian shared an adorable photo  of him and Nikki with two of their dogs with a heartfelt caption, writing, "A day with 3 of the most beautiful ladies in the universe."
Joe Manganiello and Sofia Vergara
Joe Manganiello and Sofia Vergara reportedly hooked up  over the Fourth of July weekend after meeting for the first time at the White House Correspondents' Dinner in May; at the time, Sofia was engaged to longtime boyfriend Nick Loeb — they ended their relationship in May — and Joe was newly single after splitting from Bridget Peters back in March. These two were arguably the sexiest couple of the Summer, and they wrapped up the season with a romantic trip to Cabo San Lucas, Mexico , over the Labor Day weekend. Most recently, Sofia joined Joe on the set of Magic Mike: XXL in Georgia, and the two were spotted on a double date  with Joe's costar Channing Tatum  and his wife, Jenna Dewan.
Jennifer Lawrence and Chris Martin
Established: June Split: October
Jaws dropped in early August when rumors of a relationship  between Jennifer Lawrence and Chris Martin  first made the rounds. Multiple sources reported that the couple had been cozying up since June, not long after Jennifer called it quits with her ex, Nicholas  Hoult. Meanwhile, the Coldplay frontman and his wife, Gwyneth Paltrow , famously announced their "conscious uncoupling" back in March.
While dating, Jennifer took in Chris's concerts — including his performance at the iHeartRadio Festival  — and the couple was spotted boarding a private jet together  in LA. Sadly, the music died for this couple, as they parted ways in late October . We can't wait to see which lucky guy lands Jennifer next!
Zac Efron and Michelle Rodriguez
Established: July Split: August
Michelle Rodriguez and Zac Efron 's budding relationship definitely took us by surprise: the duo went on vacation with a group of friends  in Italy and logged lots of time together on the beach. During the Fourth of July weekend, they shocked everyone when they were photographed kissing and cuddling  on a giant yacht in Sardinia. Michelle was most recently linked to model Cara Delevingne and Zac was reportedly dating his Neighbors costar Halston Sage in April. Sadly, the couple's Summer romance came to an end in August after they reportedly got into a fight  while in Ibiza, Spain. A source told Us Weekly that "Michelle is going to do her own thing," adding, "Zac knew this about her when he got with her. He's very into her though, and perhaps more than she's into him."
Samira Wiley and Lauren Morelli
Orange Is the New Black star Samira Wiley and Lauren Morelli, a writer for the hit Netflix show, began their relationship back in April but didn't make their first public appearance as a couple until the Emmy Awards in August. The following month, Lauren filed for divorce from her husband  of two years, Steve Basilone. Hopefully we'll have many more opportunities to see Samira and Lauren out and about together.
Cameron Diaz and Benji Madden
Rumors of a new romance for Cameron Diaz  began in early May after she hit the gym with Good Charlotte guitarist  (and Nicole Richie 's brother-in-law) Benji Madden. After their gym date, they both attended an A-list book party with Nicole, Joel Madden , and Gwyneth Paltrow . If their sweet PDA-filled stroll  in June wasn't confirmation enough, Cameron and Benji took their love to the next level when they were spotted getting cozy on the beach  in Miami over the Fourth of July weekend. As of October, Benji and Cameron's relationship was so strong that sources have reported  they're planning to get engaged.
Robert Pattinson and FKA Twigs
Since they began dating in late Summer, Robert Pattinson  and FKA Twigs have taken their love all over the globe, popping up in LA; Paris; Brussels, Belgium; NYC; and most recently, Miami. While their relationship hasn't been without controversy — the British singer was the target of online bullying, receiving racist messages  via Twitter — it's been hard to ignore how smiley and happy Robert seems with his new lady, and their aww-inducing PDA  has made us pretty thrilled, too. As their romance seems to be going strong, we can hopefully look forward to many more outings (and maybe even a red carpet debut!) for these two in the coming year.
Lea Michele and Matthew Paetz
Lea Michele  and Matthew Paetz struck up a romance after meeting on the set of her "On My Way" music video back in April. As rumors of a relationship between the two spread in July, reports about Matthew's alleged past as a male escort  emerged. Since then, the couple has been spotted around LA on hikes and daytime outings, and they even took a PDA-filled trip to Italy  together over the Summer. Most recently, Lea confirmed their status on Instagram when she shared a photo  of their shadows holding hands with the caption, "To love and be loved is to feel the sun from both sides."
Khloé Kardashian and French Montana
Established: April Split: September
Khloé Kardashian and NYC-based rapper French Montana were spotted on multiple nights out together in early April. Rumors of a romance between the two gained steam when Khloé shared Instagram photos  while taking a private jet to Phoenix, AZ, to attend one of French's performances. Since then, they were pretty much inseparable; not only did French throw Khloé a lavish 30th birthday party on a boat  in NYC, but he also bought her a brand-new Jeep for the milestone and accompanied her to a celebration in Las Vegas over the Fourth of July weekend. Alas, the relationship didn't last; Khloé and French split in September and a source confirmed to E!  that Khloé grew weary of his "needy, obsessive" behavior, adding, "It just wasn't working out."
Aaron Rodgers and Olivia Munn
Just a couple of weeks after her split from actor Joel Kinnaman, Olivia Munn reportedly moved on to Green Bay Packers quarterback Aaron Rodgers. The two were together at the Academy of Country Music Awards in Las Vegas in April and were spotted "stealing kisses" during a night out in Malibu weeks later. In early June, we spotted them stealing some kisses on the set  of Olivia's show The Newsroom, and Aaron accompanied her to the screening of her latest film, Deliver Us From Evil, later that month. As of late September, the two were still going strong, so much so that Packers fans had taken to blaming Olivia whenever Aaron makes a bad play  on the field.
Joseph Gordon-Levitt and Tasha McCauley
Joseph Gordon-Levitt went public  with his relationship with Tasha McCauley in May. She is the cofounder and CEO of Fellow Robots, a robotics company based in Silicon Valley that focuses on products for retail stores.
Big Sean and Ariana Grande
Ariana Grande and Big Sean's romance was first brought to our attention in August, when backstage cameras at the MTV VMAs caught the couple holding hands  after Ariana's performance. Both Ariana and Big Sean were coming fresh off big relationships — Ariana split with her on-again, off-again YouTube star boyfriend, Jai Brooks, in early August, while Big Sean famously split from Naya Rivera in April (Naya went on to get married to Ryan Dorsey three months after their breakup). In October, Sean and Ariana shared a smooch  while on Universal Studios Hollywood's Revenge of the Mummy ride and Ariana confirmed that they were an item, telling Ryan Seacrest  during an interview, "I guess [we're dating]."
Britney Spears and Charlie Ebersol
Britney Spears  has had more than her fair share of heartbreaks; in August, the singer split from boyfriend David Lucado  after he reportedly cheated on her. She began dating Charlie Ebersol, a TV producer from a Hollywood family, a couple months later. "They met through friends," a source said about the relationship . "He is the sweetest guy ever, and they are very much enjoying getting to know one another. They are both very happy and having fun." Britney has since confirmed the news with adorable pictures she's shared on Instagram, including snaps of Charlie hanging out with her two sons, Sean Preston and Jayden James.
Zac Efron and Sami Miro
After his Summer fling with actress Michelle Rodriguez, Zac Efron  moved on to model and wardrobe stylist Sami Miro. The couple was spotted together in Denmark in September before attending and LA Dodgers game and Halloween  party together, where they left holding hands. The couple took their relationship to the next level in late November; they were spotted leaving a pet supply store  with an adorable black puppy in tow, and Sami confirmed via Instagram that the two had adopted the dog together.
Scott Eastwood and Brittany Brousseau
New Hollywood heartthrob Scott Eastwood reportedly went off the market in May  after being spotted "holding hands and showing other PDA" with model Brittany Brousseau at a Nylon magazine party.
Malin Akerman and Colin Egglesfield
Malin Akerman and Colin Egglesfield began dating in April, and a source confirmed the budding relationship after they were photographed leaving dinner together in LA. The insider told Us Weekly  that the couple is "taking it slow" and that Malin "thinks he's almost too hot for her!" OK, sure.
Miley Cyrus and Patrick Schwarzenegger
Miley Cyrus  and Patrick Schwarzenegger rekindled their romance in October after she wrapped up her Bangerz world tour. Patrick, the son of Arnold Schwarzenegger  and Maria Shriver, had previously admitted that he had a crush on the singer, and the two briefly dated in 2011 while Miley was on a break from then-boyfriend Liam Hemsworth. The couple made their new romance public when they were spotted sharing a sweet kiss  at the UC Berkeley vs. USC game in LA in November, and they've been staying close and showing PDA  ever since.
Kat Dennings and Josh Groban
Singer Josh Groban and 2 Broke Girls star Kat Dennings stepped out for the first time as a couple in October. They posed on the red carpet together at the Carousel of Hope Ball in LA and stuck close while inside. A source close to the actress  said that the couple is "having a lot of fun." Before being linked to the famed singer, Kat was dating actor Nick Zano, who had a guest role on her hit CBS comedy. Josh was previously linked to Mad Men's January Jones  from 2003 to 2006.
Brooklyn Beckham and Chloë Grace Moretz
Brooklyn Beckham and Chloë Grace Moretz were first linked over the Summer, when they were spotted on an adorable skate date  and attended the Teen Choice Awards  together. Although the duo has been private about their relationship, Brooklyn has reportedly been "smitten" with Chloë, and the 17-year-old actress said the sweetest things about the Beckhams  in an interview in September. In early December, Brooklyn created a Twitter account — and Chloë was the first person he followed .
