The 29-year-old, engaged to actor Jason Sudeikis, strips off for a drunken bonfire scene in the film, reports femalefirst.co.uk.
"So the next night we did the bonfire scene and I thought, 'I should probably go skinny dipping.' And I ran into the water, and I didn't know what Jake Johnson was going to do! If he follows me into the water, we'll shoot something in the water. Or he doesn't," she was quoted as saying
"But I'm just as present in the scene as the audience is, which was really fun. And Chicago is home to some of the world's greatest improvisers, so it felt appropriate that we were making the film there," she added.
