Jessica Simpson‘s loose lips have confirmed baby two is a boy! Despite not planning to reveal the sex of her second child to the world, once the singer started talking pregnancy on Jimmy Kimmel Live she accidentally said too much.

“I just feel awful, I’ve been vomiting,” she told the host about the differences in her second pregnancy. “The crazy thing is, I never knew that a wiener could actually make me nauseous.”

Gasp! Noting her mistake, Jessica Simpson confirmed, “Well, I guess I just told the world that I’m having a boy!”

The stunning star, seen here in a Twitter pic, later added:

“I can’t believe I did that; that was not planned … I just did it so crude, too. That was awful. I’m talking about wieners.”

After baby boy arrives, the singer and fiancé Eric Johnson don’t plan on having any more children. She explained, “I really don’t want to be pregnant again, because this pregnancy is really rocking my world right now.”
