David Beckham visited the Experimental University School in Athens, Greece, today before traveling to the UK with the official Olympic torch. David, Princess Anne, and various Olympic officials boarded an Airbus dubbed Firefly and embarked on a four-hour flight with the Olympic torch, bound for an airfield in Culdrose, Cornwall. Expressing his gratitude and excitement, David posted a heartfelt message on his Facebook wall, "What an incredible moment, very proud day for me and so excited for the country."

The torch will make its way across the UK during a 70-day relay before returning to London for the Summer Games opening ceremony. It's been a week full of memorable events for David. David and the LA Galaxy were honored at the White House on Tuesday for their MLS Cup win, and in addition to bringing the torch to his home country, he was also nominated in the category of choice male athlete at this year's Teen Choice Awards.

Joshua Jackson and Diane Kruger arrived hand in hand for the Haiti: Carnival in Cannes event on Friday. Diane wore a stunning navy chiffon gown by Jason Wu, while Joshua looked dapper in a black suit and bow tie. The event, which was presented by Giorgio Armani, supports Sean Penn’s J/P Haitian Relief Organization and Paul Haggis's Artists For Peace and Justice, as well as Petra Nemcova's Happy Hearts Fund. All three charities have helped to provide aid and improve living conditions since the 2010 earthquake in Haiti, and the Carnival in Cannes fete brought a star-studded crowd together to raise money for the cause.

Other Cannes attendees like Jessica Chastain, Gerard Butler, and Chris Rock also showed up for the ritzy gala and partied alongside Josh and Diane. Diane's gig as a juror has kept the couple busy at the film festival this week. They had a fun-filled time at the Calvin Klein Cannes bash last night, which also brought out Naomi Watts and Isla Fisher.

Julia Roberts and Danny Moder were arm in arm at the Jonathan Beach Club in Santa Monica last night. They paired up for Heal the Bay's Bring Back the Bay charity event, which also brought out Amy Smart, Ali Larter, and Julia-Louis Dreyfus. Julia wore a polka-dot Moschino jumpsuit to the fundraising gala, where she and her husband Danny were honored along with Amy for their leadership and environmental accomplishments. Amy's husband Carter Oosterhouse was on hand for support. Julia is coming off a busy few months that included promoting Mirror Mirror with costar Lily Collins and premiering Jesus Henry Christ with Michael Sheen. Julia was able to fit in family time, though, and took a Hawaiian vacation with her kids Hazel, Phinneaus, and Henry.

Kristen Stewart and Charlize Theron stopped by the Spanish show El Hormiguero during their trip to the country yesterday. The Snow White and the Huntsman costars were up for a variety of fun tasks including a science experiment that required them to wear eye protection and gloves. Their time in Spain wasn't all goofy though, since Kristen and Charlize dressed up for a more serious appearance in Madrid. Kristen's time in front of the cameras will continue when she arrives at the Cannes Film Festival to promote On the Road soon. The festival is already underway and there have been plenty of stars hitting the glamorous red carpet, including Eva Longoria, Diane Kruger, and Marion Cotillard.

Kate Middleton, the Duchess of Cambridge, was the lucky lady hanging out with both her husband, Prince William, and his little brother, Prince Harry, today! The trio attended a reception in London's Waterloo Chamber ahead of a lunch for visiting monarchs at Windsor Castle. Kate Middleton wore a dress from Emilia Wickstead, a pale pink coat-style frock that costs nearly $2,000.

At the meal, Harry, William, Kate, and Queen Elizabeth mingled with kings, queens, and heads of state from 26 countries. William and Harry's cousins, Princesses Beatrice and Eugenie, were also on hand to chat with dignitaries like Monaco's Prince Albert and Princess Charlene and Jordan's King Abdullah and Queen Rania. There may be protests in England this evening, though, as some aren't thrilled the royals included the King of Bahrain, who's accused of committing human rights abuses during a recent period of unrest in his country. British fare was served to Kate, William, their family, and guests, starting with a poached egg tartlet and then a main of Windsor lamb. This evening, William's father Prince Charles is hosting a dinner reception with his wife Camilla, Duchess of Cornwall.

Salma Hayek, Jessica Chastain, Naomi Watts, and Jada Pinkett Smith each made their own style statement on the red carpet at today's Cannes Film Festival premiere of Madagascar 3: Europe's Most Wanted. The ladies joined several of the animated movie's male stars for the debut following a photocall for the film yesterday. Salma arrived at the premiere in Gucci. Meanwhile, Ben Stiller, David Schwimmer, Chris Rock, and Martin Short — who all lent their voices to the project — were decked out in tuxes. Sacha Baron Cohen, who has been busy promoting his film The Dictator, wasn't able to join the group for the festivities, despite voicing the lemur King Julien XIII in the franchise. We're live on the scene at the annual celebration of cinema this week, so if you've missed any of the action, catch up with our gallery of all the Cannes Film Festival pictures so far!
