The Fashion Star mentor and Eric, 32, have already chosen a name for their daughter, although they have decided to keep it a secret for now.

Appearing on The Ellen DeGeneres Show, Jessica said: We're not really saying it [publicly] until the baby is here. We've been calling her by name. She reacts to it.

"I could be one of those psycho moms that just thinks one little kick is her really listing to me. She's really like, 'Shut up!'"

She told Ryan Seacrests radio show: "I am definitely 'feeling intimate. I'm kind of unstoppable right now. The Big O is, like, the biggest O ever!"
