In a recent feature found on the newest issue of Interview Magazine, Justin Timberlake chatted up with Mamma Mia! star Amanda Seyfried. And boy, did she reveal much more than he bargained for!

During the interview, the pair discussed Justin's love for acting, and Amanda's love for music. And that's when she revealed: "I think I should mention that I'm not wearing any clothes, I'm most comfortable in my birthday suit."

Unfortunately, this was all done over the phone so that means Justin didn't get a glimpse of Amanda's goodies. Too bad really... You can catch the full interview here.
