We count ourselves among Tina Fey's biggest fans. We've loved her since 'Saturday Night Live,' never miss an episode of '30 Rock,' have seen 'Mean Girls' about 100 times and picked up our copy of her new book 'Bossypants' the week it hit bookstores.

We also never miss one of Fey's always-entertaining interviews. So we were a bit surprised this morning to find out that Fey told Ellen DeGeneres, in an interview airing today, that she didn't intend to find out the sex of her unborn baby, because, well, she told David Letterman on Friday's 'Late Show' that she already did.

Check out the evidence below.
