Jessica Simpson's Party Dress Puts The Little In LBD

Jessica Simpson sure knows how to make an impression!

On Sunday, the mom-of-two shared a sexy Instagram photo of herself and two friends all gussied up for a night on the town.

"After the prez it's the after party #whcd @usatoday," the blond bombshell captioned the pic, in reference to the White House Correspondents' Dinner that she attended with fiancé Eric Johnson.

Jess, who wore a white floral Carolina Herrera gown at the dinner, changed into a showstopping strapless LBD with a thigh-high slit and a low neckline that flaunted her curves for the Bloomberg Vanity Fair after-party.

The 33-year-old completed her look with a bouffant hairdo, a smoky eye and a serious model pout.

It's a good thing the singer/fashion designer looked so amazing because ex-boyfriend Tony Romo and his wife Candace Crawford was also at the White House Correspondents' Dinner, although the pair reportedly didn't stage a reunion.

Jes knows that looking good is the best revenge!
