Halle Berry & Olivier Martinez -- Dine and Dash

Halle Berry and Olivier Martinez didn't waste any time after Thanksgiving dinner at a friend's house last night -- beating a hasty retreat back home in the wake of Olivier's blowout fight with Gabriel Aubry.

TMZ broke the story ... Gabriel was arrested for misdemeanor battery yesterday after a violent showdown with Halle's fiance at the actress' home.

Both Gabriel and Olivier went to the hospital after the fight -- we're told Gabriel suffered a broken rib, contusions on his face, and possibly a more serious head injury.

Meanwhile, Olivier roughed up his hand ... but appears to have emerged victorious in the melee.
