Mario Lopez

Mario Lopez wed longtime love Courtney Mazza in an oceanside ceremony near Punta Mita, Mexico, on Saturday. Their 2-year-old daughter Gia served as the flower girl for the event, which took place at Joe Francis's estate. Courtney wore Ines Di Santo. Among the guests was Mario's very good friend Eva Longoria, who wore a blue gown, and her mother. Eva shared a few photos of herself getting ready for Mario's gorgeous I Dos and ended up slipping off her shoes to dance with Gia. There was a mariachi band to entertain the guests and a Winter-wonderland-and-beach-themed cake, which Mario and Courtney posed in front of with Gia.

Reid and new hosts Khloé Kardashian and Mario Lopez, who brought along his fiancée, Courtney Mazza, Brit and Demi hung out at a party for the program's finalists at The Bazaar inside the SLS Hotel Beverly Hills. Britney, Demi, L.A., and Simon Cowell are now faced with whittling down the remaining 12 contestants to one winner — we'll see the latest developments in the X Factor drama on tomorrow's episode. Before then, though, the gang celebrated together yesterday with Brit's fiancé, Jason Trawick. Now, Demi's got her attention on today's 2012 election. She tweeted late last night, "My first time voting! Make sure to vote! Every vote counts."

Sports Illustrated's Kate Upton posed with her illustrious new magazine cover at Las Vegas's Pure Nightclub yesterday. She's the lucky lady fronting the annual Swimsuit Edition, following in the footsteps of last year's model Irina Shayk. The winner was revealed Monday, when Kate's sexy Times Square billboard was unveiled during The Late Show. Since then, Kate's been on the go with Chrissy Teigen and Anne V. For last night's party at Pure, Chrissy was joined by her fiancé, John Legend. Kate hit the bash solo, but she may be off the market. Kate Upton's dating Mark Sanchez, the Jets quarterback, according to reports. She hasn't confirmed the stories but did say that "he is cute" while chatting with Ellen DeGeneres recently.

Jessica Alba brought a pop of color to her Extra interview with Mario Lopez at The Grove in LA yesterday. She wore a green blazer for the appearance to talk up her new line of eco-friendly home products. Jessica just launched The Honest Company this month and she's been busy chatting about the business, which she's been working on for three years. While Jessica was promoting her latest venture, her husband Cash Warren was spotted out with their daughter Honor. Jessica and Cash took a break from their busy schedules to attend a fashionable event in Las Vegas last week. They were just a few of the stylish stars at Chanel's dinner to celebrate Numéro Privés at the Wynn Hotel, where Jessica chatted with stylist Brad Goreski and his longtime partner Gary Janetti.

Kim Kardashian and Kris Humphries's wedding was a star-studded affair in Montecito last night. Guests like Ryan Seacrest and Julianne Hough were spotted on their way into the event, and once the party wrapped up, the attendees headed out of the private estate. Demi Lovato left in her car solo while Lindsay Lohan and mom Dina had a driver. Mario Lopez and his girlfriend Courtney Mazza were decked out in black and white as they waited for transportation alongside other partygoers. Kim's sisters Khloe Kardashian and Kendall Jenner changed out of their glamorous Vera Wang gowns and into white track suits, while Bruce Jenner still had on his bowtie as he made his way off the property. Their big day may be over but there's more fun in store for newlyweds Kim and Kris, who will celebrate their marriage with another bash in NYC later this month.

Eva Longoria stepped out in bright white short shorts and a blazer on Saturday as she met up with Mario Lopez at her Hollywood restaurant Beso. Eva and Mario's lunch meeting was filmed, and the longtime friends were apparently taping for the new celebrity reality series H8R, which Mario is executive producing. It was recently announced that the eighth season of Desperate Housewives will be the show's last, and while Eva and the other stars of the show have expressed sadness over leaving Wisteria Lane, it appears that Eva is already starting work on new projects. Mario's CW series, which features celebrities being confronted by people who don't like them, will feature Eva Longoria as one of the stars who goes head to head with a "hater." Kim Kardashian and Snooki have already starred in their own episodes of the show, which is set to debut this Fall.

Kristen Bell was also there to promote her upcoming Showtime series House of Lies while Kat Dennings was there for her "edgy" CBS comedy Two Broke Girls.
