AnnaLynne McCord set floral dress 90210

AnnaLynne McCord glammed it up on set of 90210 in a floor-length black silk floral gown.

Who knew the sexpot could look so refined?

The 25-year-old starlet paired her gorgeous gown with a simple canvas bag. Guess she can't resist incorporating a bit of her hippy-style even while all dressed up.
