Some of the year's hottest movies will debut at the Cannes International Film Festival, but the annual event also draws the hottest couples.
Josh Brolin showed off his new fiancee, model Kathryn Boyd, on the red carpet for Sicario. The model flaunted her square cut diamond ring after Brolin's secret proposal. This would make Brolin's third time at the altar, after failed marriages to Alice Adair and Diane Lane.
Another star seen moving on was Robin Thicke, who showed up all smiles with his model girlfriend, April Love Geary. Just two years ago, Thicke was attending the festival with his now ex-wife Paula Patton.

Leonardo DiCaprio and Paris Hilton had a moment when The Wolf of Wall Street star outbid the socialite for a blue Chanel purse, paying $13,600 for the bag, which went to his mom.
