The sexy House actress could be seen jumping around in the surf wearing a skimpy green colored bikini then posing for some family photos.
Olivia is starring in the highly-anticipated Disney film TRON: Legacy, which is due out later this year.
Meanwhile, the 26-year-old actress is looking more fit than ever having to film her first ever nude scene in Cowboys and Aliens with Harrison Ford and Daniel Craig.
“We just finished shooting Olivia Wilde naked in front of a bonfire in front of 500 Apache warriors,” an enthusiastic Adam Beach, who plays Harrison’s henchmen in the sci-fi western, as been quoted as saying. “That was beautiful. You won’t get to see what I saw, but you’ll get a glimpse.”
When asked about the nude scene, Olivia could do nothing but laugh. “Did Adam Beach talk to you? Adam Beach is the best. Last night, we did a scene where I’m naked in front of a group of couple hundred Apache. Pretty amazing, pretty interesting.”
Not that she’s only wild west cheesecake in the film, due out next July. “I do kick-ass in this. I love doing action movies … This movie is so much fun for me.”
