Moms-to-Be Who've Dared to Bare!

From Kelly Rowland and Christina Aguilera to Shakira and Jessica Simpson, see which stars have stripped down to belly basics

KELLY ROWLAND

A model of pregnancy fitness, the singer (who is expecting her first child, a boy, with husband Tim Witherspoon) has been working out with a trainer five days a week throughout her trimesters. And her hard work shows: In October, the mom-to-be posed for ELLE.com with nothing but some light drapery to show off her toned physique. "It's really – I won't say amazing – it's Godmazing [laughs] watching your body carry a human," Rowland said of shooting in the buff. "Why wouldn't you want to celebrate that? The body should be celebrated."
