Gabriel Aubry has been charged with battery after he allegedly attacked Olivier Martinez.
The Canadian model was booked with bail set at $20,000 once he was released from hospital, after being treated for a broken rib, facial contusions and a possible head injury, following an alleged brawl with his ex Halle Berry's fiance.
Andrew Smith, Commanding Officer, LAPD Media Relations and Community Affairs Group told People: "He was booked for a private persons arrest for batter. Bail is $20,000."
The fight reportedly occurred when Gabriel was dropping his and Halle's four-year-old daughter back to her mother's house yesterday morning and Olivier tried to speak to him about the ongoing custody dispute between him and Halle.
After Olivier said to Gabriel "We have to move on," the Canadian model is said to have pushed the French actor and tried to punch him in the face but Olivier blocked it and then a full blown fight broke out.
Gabriel and Halle - who split in 2010 - have been at odds ever since she tried to convince a judge to allow her to move to France with Nahla, a move which was recently blocked by the courts.
