Katrina Bowden has won Esquire magazine's 'Sexiest Woman Alive Madness' poll.
The '30 Rock' star beat Kim Kardashian to the title in the readers' online vote which was run by the US version of the men's magazine.
Over two million votes were cast, and Katrina admits she is surprised she won.
She said: "I was up against Kim Kardashian. And then - let's put it this way, if you say my name and then say Megan Fox's name, most people know who she is but, well, a small per cent will know who I am. I think a lot of the fans of '30 Rock' kind of went crazy with it."
Katrina takes the title from last year's winner Brooklyn Decker, and believes the skimpy outfits she wears as Cerie - who is the personal assistant to Tina Fey's character Liz Lemon - in '30 Rock' helped her gain a lot of votes.
She added to Esquire.com: "Yeah, she hardly wears anything. Just those denim skirts that are barely covering her. They're like napkins.
"I do love bright colours - that's one thing I have in common with Cerie. But she dresses more how I dressed when I was in high school, when I wore really short Abercrombie and Fitch skirts and tank tops."
