One hot mama! Olivia Wilde flaunted her taut and toned bikini body while vacationing in Hawaii with her family — including fiancé Jason Sudeikis and their 19-month-old son, Otis.
On Saturday, December 12, the Meadowland actress, 31, modeled a tangerine two-piece with a halter top and cheeky bikini bottoms — all the better to show off her gorgeous frame. The brunette beauty also added a floppy hat and a striped towel as a sarong.
After a midday break from the beach, Wilde, who welcomed Otis in April 2014, made a quick change into a slate swimsuit, covered up by a sheer white top with tassels. She also rocked an underwire bra top and bottom in "Rainbow Multi" by Mara Hoffman that Sunday.
The beauty even took to the high seas for a little paddleboarding action, dressed in a printed tank and square shades.
Wrapping up the weekend, the House alum took to Instagram to share a snap from her travels that featured Otis staring out at the ocean — butt-naked! Appropriately, she captioned the pic, "Naked Cowboy."
