Sara Jean Underwood

We thought no one could ever take the place of Olivia Munn in our hearts, but Sara Jean Underwood made for a pretty capable understudy as a guest host on G4 TV's Attack of the Show! Then she became a regular presenter following Munn's departure, and the 2007 Playboy Playmate of the Year continues to give us a compelling reason to set our DVRs. The adorable and leggy blonde is also an avid yoga enthusiast and professional poker player, but no matter what she is up to, we're always interested in seeing more of her.

 

  Anne Hathaway

As the new Catwoman in The Dark Knight Rises, Anne Hathaway has big stilettos to fill. But while it takes guts to wear a tight leather catsuit on IMAX, Hathaway has never exactly been shy. And that's one of the things we love most about the Devil Wears Prada star. From spending the better part of Love and Other Drugs in the nude to gamely co-hosting the Oscars with a seemingly stoned James Franco, Hathaway has always shown a willingness to take risks. And even if they don't always pan out, she's all the hotter for it.
