Jessica Simpson Shares Adorable Photo Of Baby Ace

Jessica Simpson has one seriously adorable family.

The 33-year-old singer shared a new photo of her baby boy, Ace Knute, with her Twitter followers on Saturday, Jan. 4. In the black and white photo, the 6-month-old is seated in a swing wearing some cozy sweatpants, giving the camera a serious pose.

"My snuggle bug...," Simpson captioned the snapshot.

The star, who is set to marry fiance Eric Johnson this year, was thrilled to have a boy after daughter Maxwell, 18 months.

“I’m so excited to have a son,” Simpson told People magazine last year at her baby shower. “I didn’t grow up with a brother and I think the unknown is really exciting. I can’t wait to have that connection with our little man.”
