“I never knew that a wiener could actually make me so nauseous,” the 32-year-old queen of the loose lips said when the talk show host asked how she was feeling during her second pregnancy. She then burst out laughing and covered her mouth with her hand.

“Wait … what did you intend to say there?” Kimmel asked her.

“Well, I guess I just told the whole world that I’m having a boy,” Simpson replied with a smile.

“Oh – I didn’t even know what was happening,” Kimmel laughed.

As the audience cheered, the “Fashion Star” went on to say that luckily had already confided to her family and friends that she has a boy on the way – and she was glad she did!

"I can't believe I did that," she said about her accidental admission. "That was not planned."

When Kimmel brought up the report in Us Weekly that the baby will be named Ace, she didn’t deny it. She just giggled – a lot.

As for having back-to-back pregnancies, Simpson, mom to 10-month-old daughter Maxwell, admitted it was rough – and this could be her last baby because of it.

“I really don’t want to be pregnant again because this pregnancy is rocking my world right now,” she said.

It’s also giving her “pregnancy brain” – in which she has a hard time finishing a thought.

“I had it last time I was on the show too,” she said. “Mid-sentence I forget what I’m talking about.”

However, Kimmel amusingly shot back to the Chicken of the Sea queen: “You used to do that on the reality show too, so it’s hard to tell [if it’s a result of your pregnancy].”

True, true! We hope that never changes because we love that you never know what she’ll say. And we love surprise admissions … like this new gender news.
