Jessica Simpson Having a Boy: Pregnant Star Accidentally Confirms Baby-to-Be's Gender

And baby boy Johnson makes four! Pregnant Jessica Simpson accidentally broke news of her baby-to-be's gender on Jimmy Kimmel Live on Wednesday, March 6 -- in trademark Jessica fashion! The expectant 32-year-old designer and singer chatted with host Jimmy Kimmel about the morning sickness that's accompanied her second pregnancy and rattled off an off-color joke. "The crazy thing is I never knew a wiener could make me nauseous," the Fashion Star mentor quipped.

Instantly realizing what she revealed, Simpson laughed and added, "Well, I guess I just told the world that I'm having a boy!" The style mogul's son-to-be will join big sister Maxwell, whom Simpson and fiance Eric Johnson welcomed last May. "I can't believe I just did that, that was not planned," Simpson insisted of the gaffe. "I just did it so crude, I feel awful!"

And the nausea thing is no joke. "It's a totally different pregnancy. I just feel awful, I've been vomiting," Simpson said.

As Us Weekly previously reported, that little could very well go by an unconventional name: Ace. Simpson demurred when Kimmel asked about that potential moniker. "Well, let's hope it's a boy!" she quipped.

As for Simpson's back-to-back pregnancies -- and resultant stalled weddings with NFL pro Johnson -- the former reality star offered another off-color joke. "Maybe I should go back to when I was younger," she mused. "I was a virgin before I was married [to Nick Lachey], so maybe I should just completely reverse and just stop having sex all together until Eric and I actually say 'I do.'"

After the taping, Simpson acknowledge the hilarious boo-boo via Twitter, writing, "Accidental announcement tonight on @jimmykimmel!"
