American Idol Season 4 top-10 finalist Jessica Sierra was arrested early Sunday after she allegedly clocked a man on the head with a heavy glass at a café, giving him a cut over his eye. According to the AP, Sierra was booked on a felony charge of aggravated battery with a deadly weapon as well as charged with possession of cocaine, perhaps a nod to Idol's soft-drink sponsor.
