Cameron Diaz

Summer is just getting started, and already Leonardo DiCaprio has packed plenty of traveling, parties, and premieres into the past few weeks. He kicked things off with the NYC premiere of The Great Gatsby and later traveled to Cannes to party at nightclubs, take a boat trip with rumored new girlfriend Toni Garrn, and hang out with pal Cameron Diaz in Monaco. Once he wrapped up things on the French Riviera, Leo headed to Venice to celebrate the Venice Biennale, a major art exhibition that kicked off last week. Now, Leo has popped up in Paris, where he stopped to watch the French Open last Sunday and for a second time today with his friend Lukas Haas.

Lake Bell married artist Scott Campbell in New Orleans on Saturday, and a ton of her celebrity friends were in attendance. Jennifer Aniston was decked out in a short, summery dress alongside her own fiancé, Justin Theroux. Justin, who is good friends with Scott, appeared to be part of the wedding party and, at one point, was in charge of tending to the couple's dogs. Lance Armstrong is close with Scott as well and tweeted his excitement about the nuptials before heading to the big event. Cameron Diaz looked like she had some official duties to help out her friend and What Happens in Vegas costar Lake. Kate Bosworth, who also worked with Lake in Black Rock, had her man, Michael Polish, as her date. Who else was in attendance? Marc Jacobs, Eva Longoria, Josh Hartnett, and Alicia Silverstone, to name a few.

Lake wore a custom Marchesa Couture gown, and Scott was in Marc Jacobs. Lake and Scott met on the set of How to Make It in America in 2011 and got engaged in 2012. Click through to see all the stars at Lake and Scott's wedding — congrats to the happy couple!

May was a busy time for snap-happy social stars, with the 2013 Met Gala kicking off the beginning of the month and Memorial Day launching the unofficial start of Summer — and bikini selfie season. Aaron Paul got married in California, while Kristen Stewart, Cameron Diaz, Sienna Miller, Gisele Bündchen, and many more shared a behind-the-scenes look at the Met Gala. Justin Bieber reignited romance rumors with Selena Gomez when he posted a picture of them snuggling in his hotel room, while Drake announced his cameo in the upcoming Anchorman: The Legend Continues by sharing a photo of himself in costume with Judd Apatow. Meanwhile, stars like Rihanna, Bar Refaeli, and Lea Michele showed skin on their social networks while vacationing and modeling Summer clothes.

There's no way we could ever look as good as Cameron Diaz, right? According to Cameron's trainer Teddy Bass, that way of thinking is just plain wrong. "I wish that more people would look at celebrities and the trainers who work with them and use that as encouragement to work out," Teddy said at a recent event hosted by Asics America. It sounds easy enough, and according to Teddy, it is — and you can do it all in the comfort of your own home. "Everyone says they don't have time, but that's not true," he says. "These moves can be done in under 30 minutes, and all you need are basic household items — everyone has a couch; everyone has a table!"

If you're lusting after Cameron's arms and legs, then grab a chair and get ready to work. Do these moves throughout the day, or run through the exercises two to three times to get a solid strength-training circuit in for the day.

James Lipton raised quite a few eyebrows this week when he admitted that he used to work as a pimp in the 1950s, but he isn't the only star with a surprising, sex-related past. Lots of stars had to get their start as nude models, exotic dancers, and more before they hit it big in Hollywood.

Cameron Diaz had a snap-happy Sunday in Monaco. She and a few friends boarded a yacht, where they took pictures of themselves and the view and also drank wine before heading to the F1 Grand Prix race in Monte Carlo. Once at the track, Cameron couldn't put down her cell phone and continued to capture the scene with her camera. She made a stop by the event following her night out with friend Leonardo DiCaprio at a Tag Heuer yacht party in Monaco. While at the bash, Leo and Cameron got to meet with Monaco's Prince Albert II as he prepared to welcome the Grand Prix to his principality. While Leo wasn't spotted at the race, celebrities like Ron Howard and Michael Douglas took their places in the stands to watch the competition. The festivities in the South of France wrapped up yesterday — in addition to the Grand Prix, the Cannes Film Festival had its closing ceremony at the Palais des Festivals et des Congrès on Sunday night — and Cameron followed suit today, catching a helicopter out of Monte Carlo.

Cameron Diaz arrived in the South of France today, just as the Cannes Film Festival prepares to wrap up the festivities this weekend. She flew out to France while taking a short break from filming The Other Woman in NYC. Cameron shot scenes with Nicki Minaj earlier this week, and her costar Leslie Mann was spotted on set yesterday.

Cameron had a chance to meet up with her old friend Leonardo DiCaprio, who has been taking part in Cannes nightlife after doing press for The Great Gatsby at the festival last week. Cameron and Leo hit the red carpet today for a Tag Heuer yacht party, and they are hardly the only stars visiting the festival — check out all the celebrities at the Cannes Film Festival before the party ends on Sunday.

Graduation season is upon us! With Summer comes the end of the school year for colleges and high schools around the country, and to celebrate, we're looking back at many of our favorite celebrities during their old-school days. Tom Cruise's picture proves he was just as much of a heartthrob back in high school, while plenty of leading ladies got their starts before an audience as cheerleaders, including Cameron Diaz. Britney Spears was out on the hardwood herself playing with her basketball team, and Tom Cruise showed an early interest in action on the wrestling team. Plus, Blake Lively liked to joke around well before she nabbed a big-screen part.
