A few days after Leonardo DiCaprio [1] was seen sharing a kiss and packing on the PDA with Nina Agdal [2] on a beach in Malibu, CA, the the Revenant actor jetted off to France to act as host for The Leonardo DiCaprio Foundation's Third Annual Saint-Tropez Gala at Domaine Bertaud Belieu. Just like the group of A-listers who attended the event last year [3], Leo's gala drew an impressive crowd. The Oscar winner [4] didn't have his new girlfriend [5] by his side, but he happily posed for photographers with Mariah Carey [6], as well as old friends Tobey Maguire [7], Jonah Hill [8], Bradley Cooper [9], and Edward Norton [10], before hitting the stage to give a speech with U2 frontman Bono. Keep reading to see more photos of Leo's big night, and then check out his recent, hilarious appearance in NYC [11]!
