CAR SLUTS: Sienna Miller

A wasted looking Sienna Miller almost flashed her Anastasia Beaverhousen while exiting her slutty car after attending designer Matthew Williamson’s party last night! Though her sheer black stockings would have prevented a full crotch shot, I bet we would have gotten a peek at something! Luckily for Sienna, she pulled it off and made it safely out the car!

Sienna's latest venture Rhys Ifansand, is in the back of the car!
