Titanic star Billy Zane and U.K. TV personality Kelly Brook – who called off their engagement in April – appeared very much "back on" at Monday night's "On the Rocks"-themed Chopard even in Cannes.
The couple posed for photos as Zane rocked his shoulders to the music and Brook stroked his head.
What's the best thing about Cannes? "It's a collision of charity, champagne and cellulite!" he told PEOPLE, earning a kiss from Brook.
Gwyneth Paltrow and director Spike Lee were on hand to present the Chopard Trophy (given each year to two up-and-coming actors). This year's recipients: Chinese actress Tang Wei and American-Egyptian actor Omar Metwally.
Christina Ricci also dropped by Carlton Hotel to introduce Andy Garcia, whose Cuban band kept the crowd rocking into the night. "They're amazing!" she raved to PEOPLE.
