Sienna Kicks Ass in 3" Heels

Sienna Miller kicked up her heels yesterday -- to let a photog have it!

The "Factory Girl" star was headed into a NYC building when she was ambushed by flashes, but instead of her usual smile and duck technique, Miss Miller opted for a camera shove perfected by her ex, Jude Law.

Sienna's technique scores a 7 on the freakout scale, but she definitely loses style points for wearing white boots with black jeans.
