Rachel Bilson almost didn’t appear in The Last Kiss because she won’t do nudity, the actress reveals in Playboy.

“Movies can be sexy or sexual without showing things,” the former O.C. star, 26, said in the issue out Friday. “It’s almost a deal breaker. The movie was rated R, and they like to put in nudity wherever they can, but I’m pretty strong willed and believe it can be avoided.”

The other thing Bilson won’t do is talk about her relationship with Hayden Christensen, even though the two have been spotted together around Los Angeles for almost a year. She will, however, defend his acting chops. “He’s an amazing guy and a fantastic actor,” she told Playboy. “In those Star Wars movies I thought other people – people who are successful and Oscar-nominated – came off looking much worse than he did. But he caught a lot of s—, which really made me mad.”
