Sandra Bullock doesn't mind stripping off on camera

Sandra Bullock revealed she has no problem with nudity.

The 44-year-old actress plays a high-powered book editor in her new film, The Proposal, who forces her assistant (Ryan Reynolds) to marry her to avoid being deported, and in one "awkward" scene, they bare all.

"This film needs my nudity to be funny," she said to Entertainment Tonight.

Ryan joked: "I thought I knew her before, but now I really know her.

"We rarely ever talk about work when we hang out with each other. Lo and behold, later we were slamming into each other stark naked on a set in Boston."

The couple toned down the physical contact for the film's Hollywood premiere however, as they just hugged each other on the red carpet.

Their real-life spouses, Scarlett Johansson and Jesse James, did not attend the showing at the El Capitan Theatre but Ryan brought his mother along instead.
