Olivia Wilde's abs are out of control!

The new mom to baby Otis, 8 months, jetted to Hawaii with her fiancé, Jason Sudeikis, to bask in the sunshine with her post-baby body. Two words came to mind: Hot mama!

Snapped right out of the ocean with slicked-back wet hair, the Her actress, 30, modeled a slim and toned physique that boasted tight ab muscles, as well as a makeup-free (and, yet, still gorgeous) face.

Her two-piece of choice: the Mara Hoffman V-Wire Bikini Top and and Ruched Side Bikini Bottom in the kaleidoscopic "Supernova Black Print" (top: $121; bottom: $110). The top tied in the back, while the bottom had a cheeky cut, revealing a flattering glimpse of her derriere.

Though the actress was indulging in a little R&R, she'll soon be back to work on her five upcoming films—and she's not slowing down anytime soon. "No, [I wasn't worried about becoming a working mother] because of the example of my mom. My mom is such a badass working mother," Wilde revealed to Glamour this past September. "That inspired me when I was pregnant. I wasn't going to sacrifice myself because I was becoming a mother."
