Jessica Simpson managed to keep us guessing over the gender of her first baby, but the singer wasn't so tactful with the sex of her second child, revealing during a TV interview that she is expecting a boy.
Speaking to Jimmy Kimmel the TV host, who fell pregnant for the second time just a few months after giving birth to her first child Maxwell, admitted her second pregnancy was still a little surreal.
"I can't believe I'm pregnant again, it's like deja vu I'm here promoting Fashion Star again," said the singer.

The Fashion Star host, wearing a lacy mini dress and hot pink flats, was just getting into the stride of her interview talking about her awful morning sickness when out came her whopping faux pas.
"Oh my gosh it's a total difference pregnancy. I just feel awful, I've been vomiting," the star admitted, before revealing: "I've been vomiting and the crazy thing is I never knew that a wiener could actually make me nauseous."
Pausing for a second, the mum-to-be laughed, grabbing her mouth while the audience cheered at the news.
"Oh, shoot, I guess I just told the world that I'm having a boy!" Jessica declared.
While talk show host Kimmel played catch, only cottoning on to the revelation moments afterwards, the 32-year-old continued: "I kind of just outed that I'm having a boy right?"
"I can't believe I did that, that was not planned."
Looks like baby Maxwell has got a brother!
