Beckinsale Flips Out

For once, a celebrity was spotted flipping the bird -- and it wasn't toward a paparazzo!

TMZ was outside actor/dancer/onetime Britney plaything Columbus Short's birthday party last night at Crustacean, where "Whiteout" co-star, Kate Beckinsale, gave the finger to another guest before driving away for the night.

The British beauty left showing off her wild side, but showed up with director hubby Len Wiseman -- carrying a large box of presents and champagne -- a gift collection that's sure to get her on invite lists for many future birthday bashes!
