She’s a mother and mogul, but don’t let the credentials fool you: Jessica Simpson is as ditzy as ever.

While the Fashion Star judge wouldn’t spill the sex of her unborn baby to Ellen DeGeneres, she accidentially did so a few hours later during another promo appearance with ABC’s Jimmy Kimmel Live.

Jessica grew to the size of a marine mammal during her pregnancy with 10-month-old daughter Maxwell. But she never knew the perils of morning, noon and night sickness until she learned that she was expecting again.

Talking about how ill she’s been during this pregnancy, Simpson blurted out:

“I never knew that a wiener could actually make me nauseous.”

A surprised Kimmel replied:

“Wait a minute…”

It was then that Jess recognized her slip-up, saying:

“Well, I guess I just told the whole world I’m having a boy!”
