Thanksgiving Beatdown

Gabriel Aubry was arrested Thanksgiving morning after a melee at Halle Berry's house, which sent both Gabriel and Halle's fiance Olivier Martinez to the hospital ... TMZ has learned.

Law enforcement sources tell TMZ ... Gabriel showed up to Halle's house with Nahla for a custodial hand-off. We're told Gabriel was still in the motor court (a rich person's word for a giant driveway) when Olivier walked up to him and said, "We have to move on."

According to witnesses, Gabriel then pushed Olivier and threw a punch at his face, but Olivier blocked it and the punch struck him in the shoulder instead. We're told Gabriel then pushed Olivier to the ground, and Olivier cold-cocked him in the face, and a struggle ensued, ending with Olivier pinning Gabriel to the ground.
