Celebs sure Cannes party

LEONARDO DiCaprio, Naomi Campbell and NBA star LeBron James were just a few of the A-listers at club king Richie Akiva and Darren Dzienciol’s after-party following the swanky amfAR gala in Cannes. Despite a disappointing season — and rumors he might be traded from the Lakers — James was having a blast, we hear. “LeBron had an amazing time walking around the party saying hi to everyone,” a source at the castle-like estate Domaine La Dilecta in Cap d’Antibes, tells Page Six. “He was being super social.” We hear that Swizz Beatz played an unreleased new song with Burna Boy, and British singer Amazonica also performed. Producer Diplo also got the crowd going — our source told us that when he “came on to DJ everyone went crazy . . . Everyone wanted to just continue the amfAR celebration all night.” The party, we’re told, was held outdoors by the pool, as well as inside the property and went till 7 a.m. Casey Affleck, Ciara, Joan Smalls, Brett Ratner and British Vogue editor Edward Enninful also attended.
