Jennifer Lawrence had a jam-packed 24 hours at the Cannes Film Festival. She kicked things off with a photo call alongside her Catching Fire co-stars Liam Hemsworth and Sam Claflin, and then Jennifer slipped into a gorgeous Dior gown for the evening's marquee premiere. On Sunday, 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 grey 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. Liam and Jennifer called it a night on the early side, leaving Catching Fire supporters to mingle with models in their Capitol finest.
