Jessica Simpson accidentally reveals that she is having a boy

During an interview with Jimmy Kimmel on his talk show, pregnant Jessica Simpson accidentally revealed the gender of her baby.

She was telling Kimmel about the frequency of her vomiting, when she accidentally said, "The crazy thing is I never knew a wiener could make me nauseous!," E! News reported.

Responding to her own statement, she said, "Oh, shush!" while Kimmel was bursting into laughter.

Simpson then said, "Well, I guess I just told the world that I'm having a boy!"

There had been rumors circulating since last month that Jessica Simpson and her fiance, Eric Johnson, were going to have a boy. >

A source told Radar Online last month that they are having a boy, as the Fashion Star host hoped.

"It’s Jessica’s dream come true, she prayed she was having a boy."

Simpson told Kimmel that she really did not know how the news was out publicly.

She said, "I don't think that a lot of stuff people say is malicious in any way, but maybe I have some friends with some big mouths."
