There's No Doubt About It: Gwen Stefani Is One Of The Hottest Mamas In Hollywood

She's one of the best dressed A-list moms so we're not surprised about Gwen Stefani's choice in clothes, but those abs?! It seems like we haven't seen those since her No Doubt days! (And yes, they look just as amazing now as they did back then!)

Gwen Stefani took her youngest son Zuma to the park in Malibu yesterday, and she turned heads in a stunning all white ensemble which showcased her rock hard abs. We still can't believe she's had two children -- the 42-year-old fashionista/singer has a better stomach than most 20somethings!
