Kate Middleton dressed down for an appearance at London's Olympic Park today. She toured the facilities and met with members of the women's hockey team. Kate, who played the sport during her time at Marlborough College, even showed off her own skills while a crowd watched despite explaining her fear that, "this is going to be so embarrassing. My brain thinks I can do all these wonderful things but my body just doesn't play ball." She wore running shoes and brightly colored skinny jeans for the athletic turn, though she arrived at the event in a blue blazer accessorized with this year's official Team BG supporters scarf. Kate's work with the upcoming Summer Games will continue since she, along with husband Prince William and his brother Harry, is an Olympic ambassador. During his Brazilian tour, Harry shared that "the three of us, my brother and my sister, will be as involved as we can be" with the world sports event.

The stars of The Hunger Games took their press tour to Paris today. Jennifer Lawrence, Josh Hutcherson, Elizabeth Banks, and Liam Hemsworth posed together during a photocall after popping up in London for a red carpet premiere yesterday. In the UK, Jennifer wore a gold Ralph Lauren gown, much like the Prabal Gurung look she chose at Monday night's world premiere in LA. This evening, though, she chose a simple black Tom Ford dress with an open back. Elizabeth Banks brought a pop of color in a berry-hued embellished outfit while Josh and Liam looked dapper in suits.

Jennifer recently addressed rumors of a feud between the Hunger Games and Twilight stars, saying that she actually contacted Kristen Stewart. Jennifer told Access Hollywood, "I just shot her an email, and was like, 'Hey, can't wait to see more as this feud unfolds!'" She "wrote me back, and she was like, 'It's fine.' So, she understood."

Angelina Jolie touched down in LA today with her oldest daughters, Shiloh and Zahara Jolie-Pitt. The trio are back from their two-day stopover in Amsterdam, where Shiloh and Zahara went sightseeing on a boat and Angelina attended court proceedings against Thomas Lubanga, a Congolese rebel. Zahara and Shiloh spent one-on-one time with Angelina after hanging out with Brad Pitt in New Orleans last week. The kids traveled with him to the Big Easy while he personally checked in on the progress of his Make It Right Foundation. Brad even hosted a fundraising event for his philanthropic organization with live entertainment provided by Sheryl Crow, Kanye West, Snoop Dogg, and Rihanna. The celebration raised more than $4 million to build homes for the residents of the Lower Ninth Ward.

After an athletic morning, Duchess Catherine changed into a ladylike gray Orla Kiely dress to join Prince Charles to visit the Prince's Foundation for Children and the Arts at the Dulwich Picture Gallery in London today. Kate Middleton showed off her hockey skills in cute red pants during a visit to the Olympic Park earlier in the day. She was representing her husband Prince William and his brother Prince Harry as well, since all three are serving as ambassadors to the Summer games. The boys are both away at the moment — William on tour in the Falklands and Harry taking care of his own official duties overseas — but Kate is doing a great job holding down the fort. Kate and the queen have made a number of appearances together in William's absence, but luckily he is expected to return from duty to get home to his wife and puppy Lupo soon.

Last night's White House State Dinner, hosted by President Obama and First Lady Michelle Obama in honor of visiting British Prime Minister David Cameron and his wife Samantha, was a star-studded affair. George Clooney brought out a tuxedo for the occasion, after testifying about his experiences in Sudan and South Sudan to the Senate Foreign Relations Committee earlier in the day. Homeland star Damian Lewis arrived with his wife Helen McCrory while Sir Richard Branson also posed for photographs on his way into the event. John Legend was on hand as a performer, but also enjoyed the dinner with fiancé Chrissy Teigen, who tweeted pictures throughout the evening, including one shot of John's shirt after he spilled on himself. The other musical entertainment came from Mumford & Sons since David and Samantha are apparently fans of the British band. Even more famous faces, including Harvey Weinstein, Anna Wintour, Georgina Chapman, and Warren Buffet, attended, so click through to see them all in the gallery!
