Kate Middleton and Prince William got animated in the stands at the Olympics in London today. They joined British Prime Minister David Cameron to watch Team GB take home gold in the men's 10,000-meter track event. The win brings Britain's medal count up to 29, behind China's 53 and the USA's 54. Kate and William have been at multiple events since the Games kicked off last week with the opening ceremonies, and they've been showing lots of emotion in the crowd. Kate and William embraced during a track cycling competition, and Kate covered her eyes while watching the swimming finals yesterday. Prince William's glad that the Kiss Cam didn't pan to them, saying, "I was absolutely dreading they were going to come and show myself and my wife, and that would have been very embarrassing."

Brad Pitt was back on the set of The Counselor in London today, sporting a sexy, slicked-back ponytail. He showed off the hairstyle after wearing a cowboy hat for filming earlier this week. Brad's putting in a few days' work on the Ridley Scott-directed movie, which also stars Michael Fassbender. We'll have to wait until next year to see Brad's work in this feature on the big screen, but we already have a glimpse at his next project, which hits theaters in October: the trailer for Killing Them Softly came out this week with a look at Brad's very serious role.

It's an exciting weekend for Brad and the rest of the Jolie-Pitt family, since Maddox is turning 11 tomorrow! Maddox's birthday has been fun in years past, with a variety of celebrations. Last year, the whole crew saw a performance of Wicked in England, and in 2010 he had a go-karting party.

Reese Witherspoon met up with a friend for lunch at Hugo's in LA yesterday. She covered her growing baby bump in a navy dress and carried a colorful bag. Reese may be hanging close to home in LA as she awaits the arrival of her third child, but her Ojai vacation house is getting plenty of attention as well. The getaway was featured in Elle Decor, with Reese sharing that the spot is "meditative and restorative." It's also apparently the location of Robert Pattinson's current hideout. He's staying there in the wake of the Kristen Stewart cheating scandal and was spotted running around the compound in recent weeks. Reese reportedly offered to let Rob visit, since the duo became friends while working on Vanity Fair and Water For Elephants together.

Lots of action went down with stars this week between dressing up on set, red carpet appearances, and showing their Olympic spirit. Prince William and Kate Middleton shared a sweet embrace as they cheered on Britain's cyclists in London while Jessica Biel and Kate Beckinsale dressed up to hit the red carpet for the LA premiere of Total Recall. Brad Pitt got into his cowboy gear on the set of The Counselor in England and more photos of Kristen Stewart's secret PDA meetup with director Rupert Sanders were revealed.

Ryan Gosling hopped on a flight from New Orleans to NYC's JFK yesterday. While he's traveling, his girlfriend, Eva Mendes, is back in LA and took his dog, George, for a walk Thursday. Ryan's on the go during a break from his work schedule, which was originally going to have him promoting Gangster Squad around this time. The movie's release date was pushed back until next year, though, so Ryan will instead focus on the press for The Place Beyond the Pines. The project, which also stars Eva, will debut at the Toronto International Film Festival in September.
