Reese Witherspoon's Revealing 'This Means War' Premiere Dress (PHOTOS)

It was a girls' night out Wednesday evening as Reese Witherspoon and Chelsea Handler stepped out for the Los Angeles premiere of "This Means War," the pair's new romantic comedy.

But you'd never guess that Witherspoon is a 35-year-old mom of two from her daring red carpet ensemble. The bubbly blonde and self-proclaimed "good girl" posed for photographers in a skintight strapless dress, showing off her decollete and flashing a bit of leg to boot.

Handler similarly bared her toned gams, but covered up on top in a long-sleeved, striped dress. There's no doubt that these bombshells stole the spotlight from their male co-stars, Tom Hardy and Chris Pine, on the step-and-repeat.

"This Means War" hits theaters on Feb. 17.
