Justin Bieber Shirtless Pictures

Justin Bieber was shirtless for an afternoon out in Miami yesterday. He soaked up the sun during what was a busy day work-wise — Justin was tweeting a countdown to the release of an acoustic version of his album Believe today. Justin also attended a meet-and-greet session with a group of Florida fans.

The record also includes three new songs. One of the tracks, "Nothing Like Us," is about his split from Selena Gomez. Their split became public about a month ago, and apparently Justin's taking it rather hard. Justin admitted he's sad in an interview with Billboard, saying, "I'm not in the happiest place that I've ever been. I'm trying to get through what I'm going through. Like I said, I have my really close friends to cheer me up and keep me going."

Justin Bieber performed shirtless in Salt Lake City on Saturday in his first public appearance since his smoking scandal. He had a hectic weekend after pictures of Bieber smoking an unidentified substance were published. Justin hasn't addressed the incident directly, but he did tweet about how he is "growing and learning" and "trying to be better" shortly after the photos surfaced.

Justin also seemingly confirmed his recent split with Selena. Justin retweeted a fan who said that she thinks one of Justin's new songs will be "about breakups." Although the tweet didn't directly address Justin and Selena's relationship, some fans took it as a confirmation of a split. However, there were some bright spots for Justin over the past few days — Justin met up with a young fan with cancer in Salt Lake City after learning that she was too sick to attend his show.

Justin Bieber grabbed lunch with friends in West Hollywood on Friday and later hopped on a flight to Cabo, where he met up with friends, family, and girlfriend Selena Gomez. Justin took a shirtless walk on the beach Saturday, but didn't show off his new Jesus leg tattoo. He did, though, lounge poolside with Selena. The pair are enjoying another romantic stay in Mexico following a loved-up getaway in December. Justin might have to cut this vacation short since he's up for a People's Choice Award. The show airs Wednesday night from LA, and we'll be streaming live from the red carpet! Be sure to follow us on Twitter and Instagram for all the latest behind the scenes news and photos.

Justin Bieber and Selena Gomez got in more tanning by the pool in Cabo today. Selena wore another bright bikini after lounging with shirtless Justin earlier this week. The couple have had plenty of time to relax during their Mexican vacation, but the trip also included an exciting celebration. Selena was a bridesmaid in her friend Shannon Larossi's wedding yesterday, and while the newlyweds took postceremony pictures, Selena and Justin kissed on the beach. Their fun in the sun will soon come to an end, though, since Justin is heading to the capital for the annual Christmas in Washington show. Justin performed for President Obama during the event in 2009, and this year he'll be featured again, along with Conan O'Brien, who's set to host.

Selena Gomez was back in her bikini Friday to hang out by the pool of her Orlando hotel. She enjoyed a break from performing during her Dream Out Loud tour, which required that the starlet travel all around Florida for the past week. She was able to meet up with girlfriends later in the afternoon to indulge her inner-Harry Potter fan. Selena tweeted a photo of her and her pals drinking butter beer at the Wizarding World of Harry Potter at Universal Studios! Her boyfriend, Justin Bieber, was there to watch her first show in Boca Raton on Thursday night. He wasn't there for the pool time, but enjoyed some fresh air of his own Saturday. Justin Bieber went shirtless to check out the view from his own hotel room in Miami, greeting the morning in just a pair of sweatpants. He was soon off to hang with his pal Sean Kingston, and both guys tweeted about their shopping adventures. Selena, meanwhile, moved on to St. Augustine for a concert last night.

Justin Bieber held on tight as he planted a big kiss on girlfriend Selena Gomez in Hawaii on Thursday. The two have been all about going public with their PDA, and Justin Bieber also kissed Selena Gomez as he headed up to the stage to accept a statue at last Sunday's Billboard Awards. After the show in Vegas, the two were off on this romantic getaway in Hawaii where bikini-clad Selena Gomez and shirtless Justin Bieber wasted no time hitting the beach together. The young couple have a chaperone with them for the trip, his mom, who was along when they went paragliding in the afternoon. Still, that didn't stop them from getting especially hot and heavy in the ocean, where Selena straddled Justin for another makeout session.

Justin Bieber and Selena Gomez took their party from the sand into the water yesterday while in Hawaii. Justin Bieber was shirtless and showing off his tattoos during the day of fun in the sun with his bikini-clad girlfriend. The couple dove into the waves, but they weren't too interested in swimming — they kissed, hugged, and played around together instead! It looks like these two are all about their young love at the moment, and they even went public with their feelings by sharing a liplock at last weekend's Billboard Music Awards.
