I may not agree with her selection by Esquire readers as the Sexiest Woman Alive (I guess maybe I hadn't heard about the untimely deaths of Scarlett Johansson and Christina Hendricks), but there's no denying that Katrina Bowden is hot. She's also a recurring star on what is quite possibly my favorite show on television, which makes her a doubly-valid choice as a Desktop Girl of the Week.
The 22-year-old Bowden has only been acting since 2006 (appearing in a Fall Out Boy video before that), and is best-known for her role as Cerie Xerox on "30 Rock". Cerie has never really been given much to do as a character besides look hot, but Bowden seems to be able to handle that just fine. She's appeared in a few things outside of "30 Rock", but I've literally never seen any of them. Kind of sad, actually.
