Watch Jessica Simpson accidentally reveal the gender of HER baby, too (Slightly NSFW)

Remember Jessica Simpson's last pregnancy? What a wild ride that was. And while this one has been a little more tame (many fewer appearances on talk shows in a muumuu talking about eating PopTarts), it looks like it may get slightly more interesting.

Here she is on Jimmy Kimmel, accidentally revealing that she's having a boy. Whoops!

There were plenty of rumors that Simpson was, in fact, having a boy -- she says in the interview that she may "have some friends with big mouths," which could account for it -- but with this interview, she confirmed that indeed, she's carrying a little dude.
