Gabriel Aubry, 37, was arrested at Berry's home in the Hollywood Hills during the afternoon, the Los Angeles Times reported. Police Officer Julie Boyer said Aubry was treated for injuries to his face at Cedars Sinai Medical Center and was released on $20,000 bond.
Aubry and Berry have a child together. Boyer described Berry's current boyfriend as a "private victim" and would not release his identity, the Times said. Berry announced her engagement to Olivier Martinez earlier this year.
TMZ reported the fight began when Aubry came to Berry's house to drop their daughter off.
