Scarlett Johansson Might Just Be the World's Hottest Mom

Scarlett Johansson has the whole sex bomb look locked down — this is a woman who's won Esquire's sexiest woman alive title twice. And her sexy self just took on a new challenge: motherhood! The star just welcomed a baby girl with French fiancé Romain Dauriac, and we immediately started thinking about how her style will translate as one of hottest moms on the planet.

With a proven penchant for thigh-grazing lace sheaths and corset-style tops, we're betting she won't be giving up that signature dose of sultry siren. And since it also happens to be the new mom's birthday, there's no better time to take a look back at some of her sexiest red carpet moments.
