Halle Berry's ex Gabriel Aubry and her fiancé Olivier Martinez fight: Nastiest celebrity brawl?

A fight broke out over Thanksgiving between Halle Berry’s ex-boyfriend Gabriel Aubry and her fiancé Olivier Martinez. Apparently the brawl started after Aubry took Nahla, his daughter with Berry, to her nativity play on the day before Thanksgiving.

According to TMZ, Berry and Martinez also showed up at the play, held at Nahla’s school. Martinez reportedly whispered, "I wish I could beat the [expletive] out of you right now. You're lucky we're in a school right now. We're going to take Nahla right now and you're not going to follow us," into Aubry’s ear in French.
