Reese Witherspoon stepped onto the chilly red carpet in London on Monday for the premiere of her new action/comedy film "This Means War."

Temps were reportedly just above freezing at the Odeon Kensington, but that didn't stop the actress from posing in a short, sequined Louis Vuitton dress.

Co-stars Chris Pine and Tom Hardy were also on hand. The spy-vs-spy flick features the two actors as CIA operatives battling for the affections of a woman (Witherspoon) they are both dating. That's sure to heat things up. Check out the trailer:
