Jessica Simpson and her fiancé Eric Johnson are anxiously awaiting the arrival of their first child together. However, the happy couple are on different wavelengths when it comes to their predictions as to what they are expecting!

"I think it's a girl," the glowing mommy-to-be tells People. "But I don't know yet."

And Simpson's hunky beau is thinking differently!

"I think it's a boy," he tells the magazine. "We're pretty much at a standstill there."

Simpson and Johnson announced their exciting news in October, which many had assumed for the past several weeks as the singer's tummy kept growing. While it is her first pregnancy, Simpson, 31, recently told 'Access Hollywood' that, "Pregnancy is a friend of mine." Judging by the beautiful glow Simpson has these days, we have to agree!

"I feel great, I honestly do," she told 'Access Hollywood.' "Everything has been running smoothly. So far, so good. No morning sickness; I feel great. I’m tired, but I’m making a baby."

Rumors have suggested that Simpson and Johnson are likely to wed following the birth of their little one, who has mommy and daddy struggling to determine what color they need to paint the nursery.
