Oakland Raiders star Trent Brown -- the highest paid lineman in the NFL -- is being sued for allegedly beating the hell out of his girlfriend, who says he's a repeat attacker.
The woman behind the suit is Diorra Marzette-Sanders, who says she has a 9-month-old son with the 26-year-old.
According to her suit, Marzette-Sanders says Brown first got violent with her at a restaurant in 2018 ... slapping her face during a heated argument and leaving her mouth bloody and face bruised. She also claims he left her at the restaurant to find her own way home at 4 AM.
