Jessica Simpson Tweets Photo Of Her Baby Bump In A Hot-Air Balloon Sweater, Calls It A 'Metaphor'

Pregnancy might have taken a lot from Jessica Simpson, but at least it hasn't snatched up her sense of humor.

The 32-year-old mom-to-be posted a photo of her big and beautiful baby bump in a hot-air balloon sweater yesterday (June 3), simply captioning the picture with, "Metaphor."

Simpson, who threw her pregnant BFF Cacee Cobb a baby shower on June 2, is due to give birth to her second child, a baby boy, next month. Her daughter Maxwell just turned 1 in May.

“I don’t know [how it happened],” Simpson told Ellen DeGeneres of getting pregnant almost immediately after welcoming Maxwell. “Apparently protection was just thrown out the window!”
