Jessica, 31, waddled onto the stage in "8-inch heels" and reassured Ellen that she's not due just yet.

"I have some weeks to go," she explained on The Ellen DeGeneres Show. "I really do. It's not like tomorrow."

To be safe, Ellen had all of Jessica's favorite craving foods ready for her and a paramedic on stand-by!

"I honestly feel like I'm in a fat suit," Jessica joked.

But the Fashion Star mentor says despite her large belly, there is only one baby girl inside her!

"Believe it or not there is only one girl, but I did get knocked up by a baller," Jessica said with a laugh of her fiancé, Eric Johnson. "A big football player. That's what I get. He's like 6'4".

The mom-to-be said her doctors told her the baby will definitely weigh over 8 pounds. Jessica has picked out a name for her daughter, but Ellen still wanted to offer suggestions for a weird celebrity baby name.
