Barron Hilton, the kid brother of socialite pop crack Paris Hilton, has been busted for driving drunk like big sis.  Barron was pulled over in Malibu and booked at Lost Hills Sheriff’s Station.

Cops tell TMZ he was driving a black Mercedes on Pacific Coast Highway with a passenger — not one of his sisters– when he was pulled over at a 76 gas station.

The lush was busted at 8:30am this morning.  Can we say frat boy?

Paris was busted September 6, 2006th for DUI.  Now we eagerly await for sister Nicki to complete the trifecta.
