The 69th Venice Film Festival gets started on Wednesday, and there are plenty of hot stars expected to make the trip overseas, including Shia LaBeouf and Ben Affleck. The Italian festival has brought out lots of big names in years past, too, so let's take a look at Gwyneth Paltrow, Jon Hamm, Scarlett Johansson, and more making their mark in Venice!

Bar Refaeli soaked up the sun with friends while on the beach in Mykonos yesterday. She played on the sand and in the ocean wearing a tiny bikini that showed off her model figure. Bar covered up her two-piece to go waterskiing though. She's been relaxing on the Grecian getaway since last week and has been taking snaps of her exciting trip on Twitter. Bar's just one of many celebrities sharing pictures of their Summer fun, and she shared even more bikini moments of herself over the weekend.

George Clooney suited up to attend a special fundraiser for Barack Obama's reelection campaign in Switzerland last night. He signed autographs and posed with waiting fans on his way into the event, which was just his latest show of support for the president. George hosted a dinner at his Hollywood home in May that raised $15 million for Obama with the help of other famous faces.

George broke from his relaxing Summer in Lake Como for the Swiss function. He's been vacationing there with girlfriend Stacy Keibler on and off since June. They've both made trips back to LA and elsewhere, though, and have also invited friends to join them in the Italian city. George and Stacy played host to Channing Tatum and Jenna Dewan and were also spotted boating with pal Karen Duffy.

Hilary Duff spent a busy weekend in LA juggling family and fun. On Saturday, she stepped out with her son, Luca, who wore mini UGGs and a Beatles "Yellow Submarine" onesie, to run errands. They stopped by a Sherman Oaks mall and were later back together to pick up fresh produce at a farmers market. That evening, Hilary switched gears to attend a party at Skybar in West Hollywood to celebrate Mindy Kaling's upcoming comedy series, The Mindy Project. She wasn't the only famous face in attendance since John Mayer, B.J. Novak, and more gathered for the bash. It looks like Hilary is enjoying her downtime before getting back to work, since she recently signed a deal to star in and produce a half-hour comedy series.

Anne Hathaway and fiancé Adam Shulman linked arms, walking their dog, Esmeralda, in Brooklyn on Saturday. Yesterday was National Dog Day, and it's likely Anne and Adam spent it with their favorite four-legged friend. The pair are falling back into their East Coast routine after a busy Summer of traveling. Anne hit the road to promote The Dark Knight Rises, which has grossed over $400 million.

Coming off the success of her Summer blockbuster, Anne's now enjoying a break from acting. The free time gives her the opportunity to focus on wedding plans. Friends close to the couple say they have pushed back their wedding date to 2013 and "can't wait to get married and have babies."

Victoria and Harper Beckham were together to attend a party at LA's Giggles N' Hugs yesterday. Victoria tackled the August day in all black, while her daughter coordinated a pink dress with a pink hair bow. The whole Beckham clan is together on the West Coast after the Olympics took them to London. Victoria and the Spice Girls performed at the closing ceremony, while dad David was a part of the opening ceremony and also cheered on Team GB at many events. Now, though, David's focusing on winning his own games. He's back to playing with the LA Galaxy, and last night took the field in LA as they played against FC Dallas and won 2-2. There is more travel in the immediate future for the family — Victoria will head to the Big Apple soon to show off her latest designs during New York Fashion Week.

Cameron Diaz cozied up to a female friend outside a gym in NYC today after fitting in a workout with her trainer Teddy Bass. Teddy recently showed FitSugar how to get Cameron's toned arms, and it looks like his star client is keeping up her well-known fitness regimen in the Big Apple. In fact, Cameron is penning her own book on health and wellness, which is expected to hit shelves next year.

Cameron celebrates her 40th birthday on Thursday and got a head start on the celebrating with close friends while in LA earlier this month. She threw a baby shower for Drew Barrymore a few weeks ago, and she was also seen catching up with Portia de Rossi at a salon and dining out with one of her reps while on the West Coast.
