Cannes Film Festival

Jennifer Lawrence had a jam-packed 24 hours at the Cannes Film Festival. She kicked things off with a photocall alongside her Catching Fire costars Liam Hemsworth and Sam Claflin, and then Jennifer slipped into a gorgeous Dior gown for the evening's marquee premiere. On Saturday, Jennifer joined her boys for the official Catching Fire party. She wore another Dior — this time white with a flower detail — before switching into a gray number. Once inside the bash, Jennifer sat close to Liam, but also stayed glued to her iPhone. Jennifer also showed off her big smile while chatting with fellow partygoers.

Jennifer Lawrence and Liam Hemsworth linked up with their Catching Fire costar Sam Claflin this morning for a photocall at the extremely rainy Cannes Film Festival! The trio were able to escape the elements by posing inside the Majestic hotel. Jennifer, Sam, and Liam are in France to hype up the second installment of The Hunger Games series, which is out in the US on Nov. 22. Also smiling for the cameras were Lionsgate cochairmen Rob Friedman and Patrick Wachsberger and director Francis Lawrence.

The cast and team behind the film are busy despite the release being six months away. It was just announced that CoverGirl will launch the Capitol Collection, a range of makeup products inspired by the film. And Liam made sure to enjoy the social side of Cannes, too. Last night, he and a group of guy friends checked out the Rev Run and DJ Ruckus set at Belvedere's party inside the VIP Room club.
