Marisa Tomei uncomfortable with going nude

In the upcoming film The Wrestler, Marisa Tomei goes nude

"I'm uncomfortable with exposing myself," she tells Parade.com. "But in these films I think what I did was appropriate and I'm proud of it. Actually, I 'm concerned with a lot more than how my body looks. I just find it really hard to watch myself in general. But being nude was weird. And now I'm seeiming like the actress who does that, which wasn't my intention."

Marisa, 44, who bares an amazing figure in the film, attributes good genes and, hula hooping!

"I have a travel hoop. You can twist it in half but it's adult size, not like a little kids hula hoop," she says. "It's really good for your core strength."
