Rachel McAdams is one of the most "real" and laid back celebrites out there. Need proof? She had no qualms about stripping down for her role in The Time Traveler's Wife. In fact, she barely batted an eyelash!

When you're playing a fictional character, it's as normal and mundane as eating breakfast. What bothers me is our culture's obsession with nudity. It shouldn't be a big deal, but it is. I think this overemphasis with nudity makes actors nervous. There's the worry about seeing one's body dissected, misrepresented, played and replayed on the internet," Rachel told Parade.com.

She also gave a slight nod to exercise, or shall we say lack there of? Rachel, 30, loves her body as is and nay-says the idea of working out like a fiend.

I personally think you can have a really rich and full life with no abs. Abs are for wimps,"she joked.
