George Clooney and Stacy Keibler loaded up a boat on Lake Como yesterday. The couple took a group of friends, including actress Karen Duffy, out on the water during their latest Italian getaway. George and Stacy are back at George's vacation home after briefly traveling out of the area. George met up with pal Brad Pitt in England while Stacy headed to NYC where she attended an event and was spotted out shopping. The duo seem to be making Lake Como their Summer base, and it looks as if George has even more plans to stay overseas. George will host a fundraiser for President Obama in Switzerland this August, which may explain his recent visit to the country.

Prince William and Kate Middleton were in the stands at Wimbledon today. The royals watched Roger Federer's victory over Mikhail Youzhny — which will move him on to the semifinals — and stayed for the Andy Murray and David Ferrer match afterward. Kate, who is a big tennis fan, sported a knit Alexander McQueen dress that she also wore during her trip to Canada with Prince William last year. She leaned in close to chat with her husband and cheered and clapped during the action.

It's been 15 months since Kate married Prince William, and since then, the pair have been busy traveling the world and focusing on philanthropic efforts close to home. The whirlwind year led to Kate winning this year's PopSugar 100, beating out stars from Beyoncé Knowles to Angelina Jolie for the top spot.

Jennifer Aniston and Justin Theroux continued their European vacation with a stop in Capri last month. The couple relaxed at the JK Place hotel, where they were spotted kissing over breakfast on their balcony. Jennifer and Justin then boarded the luxurious Liberty of Lymington yacht off the coast of the Italian island. Jennifer wore a sexy bikini to lounge on the deck of the vessel, while Justin went shirtless, showing off his many tattoos. They posed for photos together and dined alfresco during their boat excursion.

The sunny getaway was just one stop on the duo's Summer trip, which also included visits to Paris and Rome. Jennifer and Justin even linked up with pals George Clooney and Stacy Keibler for a private flight, though Jen, Justin, and Stacy have all since returned to the US.

Zac Efron marked the Fourth of July with friends in the French Riviera today. The actor, sporting bright blue Ray-Bans and a mustache, was spotted having lunch with a group of guys at St.-Tropez's Club 55. The restaurant is a favorite among celebs, and after the meal, a barefoot Zac made his way down the dock and hopped in a waiting boat. Once on his yacht, Zac stripped down to show off his sexy six-pack. He lounged shirtless on the deck and chatted with friends.

This is the second trip to the South of France that Zac's made in recent months. He also attended the Cannes Film Festival in May in support of his upcoming movie The Paperboy. Zac's current trip overseas meant he missed out on his friend and former High School Musical costar Ashley Tisdale's 27th birthday party earlier this week in Malibu. Zac was on hand for the festivities last year, but this time around, Ashley celebrated with a bikini-clad Selena Gomez and her boyfriend, Scott Speer.

Ben Affleck and Jennifer Garner flashed bright smiles as they ran errands in Santa Monica together yesterday. The couple recently celebrated their seventh wedding anniversary with a romantic dinner at LA's Tavern restaurant. Since then, it looks as if they've been prepping for their youngest child Samuel's first Fourth of July with a little help from their older kids. Jennifer was out with Violet and Seraphina shopping on Monday. The Garner-Affleck family is just one of many famous groups that get patriotic, and perhaps Samuel will get to check out their neighborhood parade like the girls have done in years past.
