Hunky vampires unite! 'The Twilight Saga: New Moon' star Kellan Lutz and "Vampire Diaries" star Paul Wesley are just two of Cosmo's Fun Fearless Males, and only ET is behind the scenes with them as they shoot their new Cosmopolitan cover -- and Kellan talks about being de-fanged!

"I read the [Stephenie Meyer] books after I got the role, and I still didn't realize that we didn't have fangs until we started shooting ['Twilight']," reveals Kellan. "We were doing the hair and makeup and put in the cool contacts and I'm like, 'Guys, uh, what about the fangs?' And they're like, 'You guys don't wear fangs.' No fangs, no fun."

On newsstands January 12, Cosmo's other Fun Fearless Males -- from the big and small screen, on the field, in the recording studio and even in the operating room -- include Gerard Butler, Stephen Moyer, Chris O'Donnell, Terrell Owens, Ne-Yo, Jonathan Rhys Meyers, Nathan Fillion, Seann William Scott and Dr. Oz!
