Perez Hilton is attempting to make a big deal of this video of K-Stew getting "caught" sucking down a Heineken during some downtime on the set of Runaways. Oh, all right, she's 19, so it's underage drinking. Sure Perez. Like you weren't already an alcoholic by 19.
It's an idiotic law anyway. If you're old enough to be sent to war, you're old enough to drink. If you're old enough to be breathed on by Robert Pattinson, you're also old enough to drink. K-Stew can do whatever she wants. Perez? He needs to go take another Clearasil bath.
