Lily Allen was videotaped leaving Ronnie Scott’s in London on Monday (August 18), where the buzzed singer was being heckled by a drunken brunette. After egging on Lily with insults, she squared off with the woman and punched her. “Where is that bitch, man? I’ll fu**ing batter her,” Lily said later. But a further rumble was prevented by her friend and TV host Miquita Oliver. “Violence is bad,” Lily agreed. The punches could cause trouble for Lily if the woman decides to press charges, as she learned trying to get into the U.S. after a prior assault on a paparazzo. Check out footage from The Sun below.
