Jessica Biel has squeezed into a sexy elf costume - to help Santa mug people.

The actress got into the festive mood for a new funnyordie comedy sketch where she helps Santa turn to crime as Bleebo the elf.

The pair find they are short of cash for their festive fun so decide to go on a money-spinning crime spree.

Jessica - who hitches up her skirt to reveal a gun strapped to her thigh - uses her ample charms to lure one victim down an alley, where Santa is waiting to mug them.

The sketch ends with Bleebo and Santa running off after ambushing a pair of tough-looking thugs in a subway.

Jessica jumps in the air and clicks her heels with delight as the dastardly duo flee the scene of their latest crime.
