Leonardo DiCaprio had a busy few days at the Cannes Film Festival last week as he promoted The Great Gatsby. He teamed up with his costars Carey Mulligan, Tobey Maguire, and Isla Fisher for multiple events including the glamorous Gatsby red carpet premiere that opened the festival, but his trip to France wasn't all about work. On Friday, Leo let loose at a nightclub, where he danced with friends, including Lukas Haas, and a few lucky ladies. Leo tried to keep a low profile with his hat on, but he was spotted mingling in the crowd and showing off his moves while also smoking on an electronic cigarette.

He followed up the late-night fun by hanging out on a yacht over the weekend and today he made his way back out on the water. Leo and Lukas were joined by a group of guys and girls to lounge on Phillip Green's luxury vessel. Leo went shirtless for the excursion and even snapped a picture of himself on his phone while smoking a cigar when he wasn't busy chatting up the ladies.

Kristen Stewart appeared to be in a chatty mood when she met up with friends for dinner in LA last night. According to a source on the scene, Kristen and her friends visited an eatery in LA's hip Silverlake neighborhood. She chatted with her group while standing next to a car and our source reports that she "was in a good mood," adding that she was "talking, smiling, very relaxed." Earlier in the day, Kristen was spotted smiling and wearing glasses while riding around in a car with a pal on her way to visit an unexpected confidant — Taylor Swift! Taylor is, of course, no stranger to relationship drama played out in the public eye so perhaps some girl time with the popstar is just what Kristen needed.

Kristen's split from Robert Pattinson was reported over the weekend, and more details emerged yesterday. Things have apparently been "not great" between the couple, and now it looks like Rob even moved out of Kristen's home on Sunday. Rob packed up his truck with luggage, trash bags, and his two dogs and drove out of Kristen's gated community.

It's been a whirlwind few months for the duo, who were last seen together traveling back to the West Coast from NYC, where Kristen attended the Met Gala red carpet solo. To keep track of it all, make sure to check out Rob and Kristen's relationship timeline, starting from the beginning of their romance back in 2009.

Jay-Z and Beyoncé Knowles took a small boat out to a waiting yacht off the coast of France today. The couple was joined by Beyoncé's sister, Solange, and her boyfriend, Alan Ferguson. Their afternoon getaway comes just ahead of Beyoncé's concert in Montpellier, France, tonight. She'll be back on the stage after a day off following her Saturday performance in Milan. Beyoncé's tour may be keeping her busy, but her personal life is also keeping her in the spotlight. Rumors have been swirling for days about Beyoncé being pregnant with her second child, and both she and Jay-Z have commented on the speculation in separate ways.

Jay-Z reportedly shot down the news, responding "It's not true" to a congratulatory email sent by radio host Ebro. Meanwhile, Beyoncé posted and then removed a cryptic message on her Instagram account over the weekend. The quote said, "I can't stop the rumors from starting, and I can't really change peoples minds who believe them, all I can do is sit back and laugh at these low life people who have nothing better to do than talk about me."

It was a wild reunion for the cast of The Hangover at the premiere of the franchise's third installment in LA last night. Bradley Cooper broke from the NYC set of American Hustle to attend the big event alongside Ed Helms, and Zach Galifianakis. Newly-engaged member of the crew, Justin Bartha, was also on hand for the night of fun. The guys showed love for their costar Ken Jeong and the waiting fans, many of whom Bradley stopped to snap pictures with before heading into the screening. The ladies of the Hangover trilogy, including Heather Graham, Sasha Barrese, Gillian Vigman, and Jamie Chung all hit the red carpet as well to celebrate the film's Friday release. It'll be the first big holiday-weekend Summer movie matchup, since Fast & Furious 6 also hits theaters. If you can't decide which sequel to spend your money on, these pictures of Bradley Cooper looking hot in the Hangover Part III might help!

It's been a roller coaster of a year for Robert Pattinson and Kristen Stewart. The latest news coming out over the weekend is that they reportedly split following a tumultuous few months. Rumors about the status of their relationship have been constant since they got together in 2009, and speculation picked up steam in July 2012, when photos of Kristen kissing her Snow White and the Huntsman director, Rupert Sanders, surfaced. Since then, the Rob and Kristen romance watch has been heating up — click through to see the many milestones of their time together, starting from the very beginning!

The 2013 Billboard Music Awards, which were hosted by Tracy Morgan, took over the MGM Grand in Las Vegas on Sunday!

Shania Twain handed out the first statue of the evening to Nicki Minaj, who won top rap artist, while Selena Gomez took the stage to perform "Come and Get It."

Taylor Swift — who picked up six awards before the show even started and two more, including artist of the year, during the broadcast — was another of the evening's performers, belting out "22" after walking the carpet in a bright blue Zuhair Murad dress. Other big winners included Rihanna and Gotye, each with four trophies, as well as Justin Bieber with the milestone award.

Beyoncé and Jay-Z may have taken their controversial trip to Cuba more than a month ago, but she recently released new — and totally adorable — images of their anniversary getaway on Tumblr. Beyoncé and Jay-Z cuddled up in a few of the snaps, while Beyoncé went solo in others.

Since they wrapped up their getaway in April, it's been all about business for Beyoncé. Her bikini ads for H&M were released, she kicked off her Mrs. Carter Show world tour, promoted her voice role in Epic, and walked the red carpet at the Met Gala. While the tour continues, Beyoncé is now facing pregnancy rumors after she canceled a performance in Belgium earlier this week. She returned to the stage on Wednesday and is expected to perform in Zurich tonight. Regardless of the speculation about baby number two, one thing is for sure — these pics of her and Jay-Z are too cute, so click through to see them all!

Tiger Woods and his girlfriend, Lindsey Vonn, kicked off the week with a relaxing afternoon on the water in Palm Beach. On Tuesday, the duo went boating on Tiger's yacht, Solitude, with his kids, Charlie and Sam. Tiger lounged shirtless while he fished off the side of the vessel, and Lindsey was spotted snapping pictures from the dock in her bikini. The couple are back to Tiger's home base in Florida after traveling to NYC to attend the Met Gala earlier this month. Tiger will be on the go again soon, though, since he's set to host his annual Tiger Jam charity poker tournament in Las Vegas this Friday and Saturday.

Tiger and Lindsey have been going strong since revealing their relationship in March and have showed mutual support for each other publicly. Lindsey's had Tiger by her side as she recovers from the knee injury she sustained during the skiing world championships in Austria in February, and she cheered him on during the Masters last month.

Nina Dobrev and Ian Somerhalder were both in attendance at today's CW upfronts presentation in NYC. Nina and Ian walked the red carpet separately but during the event they shared the same stage even after news of their split was announced earlier this month. They were together for three years, though they became one of the many TV costar couples that couldn't make it work off screen when they called it quits.

Nina and Ian are in the Big Apple on behalf of The Vampire Diaries, which will air its season finale tonight — make sure to tune in for our LIVE Vampire Diaries viewing party tonight at 4:30 p.m. PDT/7:30 p.m. EDT.

David Beckham had a smile on his face as he left the Paris Saint-Germain training facilities in Paris today. It was one of the last times he'll be visiting the field since earlier today he announced his plans to retire at the end of the season. David's been in the soccer spotlight since he was 14, and he'll wrap up his successful career in his final game with PSG later this month. We'll certainly miss seeing David on the field, especially since he had a hot habit of going shirtless. Hopefully this weekend's match will provide one last glimpse at his abs — and a whole lot of cuteness in the stands from his adoring family.
