Simpson desperately wants to start a family with her football star, and has become even more interested in motherhood since her sister, Ashlee, gave birth to Bronx Mowgli in November.
A source close to the star revealed, "I wouldn’t be surprised if Jessica makes an announcement that she’s pregnant very, very soon."
For now, Jessica is thrilled to be an aunt to baby Bronx. She said, "Bronx is beyond precious. I’m over the moon with joy. Life is a beautiful miracle. Ashlee and Pete are healthy, happy, and enjoying every moment."
