Ryan Gosling popped up at his first Cannes event this evening looking dapper in Salvatore Ferragamo for the Cinema For Peace inaugural dinner honoring Sean Penn for his charitable efforts in Haiti. Leonardo DiCaprio and rumored flame Blake Lively took a break from lounging so he could stop by to say a few words while Robert De Niro, Naomi Campbell, and Uma Thurman sat in the audience. Ryan's arrival in France is later than most of the star-studded crowd as his upcoming flick Drive, costarring Carey Mulligan, is closing out the film festival. Carey debuted newly dyed brown hair this week in preparation for her next role starring opposite Leonardo in The Great Gatsby. The cast of the Baz Luhrmann remake of the classic is close to complete with Joel Edgerton now playing Tom Buchanan after Ben Affleck reportedly passed on the role last month. Carey's not the only link between Leo and Ryan, as Ryan was also momentarily romantically tied to Blake last Fall.
