The stars came out to celebrate during the Cannes Film Festival in France yesterday. Gerard Butler, Adrien Brody, and Karolina Kurková were just a few of the guests at IWC and Finch's Quarterly Review filmmakers dinner, which was held at the Hotel Du Cap. Model Karolina — who tweeted of the event, "What a night!" — and Petra Nemcová got together for a playful photo, while Gerard met up with pals Robert De Niro, Ewan McGregor, and Adrien. Petra's boyfriend, Sean Penn, wasn't by her side for this bash, though they were together for the Haiti: Carnival in Cannes event. There's been so much excitement at Cannes so far, but there's even more to come, as both Brad Pitt and Kristen Stewart are still expected to hit the red carpet this week.
