She's got another bun in the oven!

Jessica Simpson is pregnant and expecting her third child with husband Eric Johnson, Radar reports. The fashion mogul was spotted trying to hide her baby bump at JFK airport at the end of October, and had an "unusually teetotal dining" at a restaurant during her stay in the Big Apple.

Apparently the blonde bombshell and her former NFL star hubby "have been in baby-making mode for months" in an effort to save their troubled marriage. The couple allegedly haven't been spending enough time together, so Johnson seeked "companionship elsewhere" with the family nanny! The outlet doesn't say he cheated, but they are certainly implying it.

The pair are already parents to daughter Maxwell, 4, and son Ace, 3.

It's almost like Jess and ex Nick Lachey are trying to out-baby each other!
