After coming out on top in a fist fight with Halle's ex, Gabriel Aubry, the French actor was snapped with a smirk on his face outside Cedar Sinai Hospital in Hollywood.
Read up on our breakdown of the fight here.
While initially Olivier sought a court injunction to prevent Gabriel from seeing his and Halle's daugther Nahla, this has since been overturned. We can't imagine he'd be smiling about that.
Gabriel currently has a restraining order against Olivier, obtained shortly after the scuffle. Thoughout all of this, Halle has remained coy.
