Jessica Simpson Debuts Baby Ace On The Cover Of Us Weekly

Talk about a picture-perfect family!

Jessica Simpson has debuted her baby boy, Ace Knute Johnson, on the cover of Us Weekly magazine with an adorable photo featuring mama and sister Maxwell. In the pic, taken at her Hidden Hills, Calif., home on Aug. 12, the 33-year-old smiles while holding her 15-month-old daughter and infant son, born in June via Caesarean section. Blond hair and full lips seem to run in the family.

"With two kids, we have our hands full, but every day is a new adventure," she told Us. "It's fun! I feel very at peace with being a mom."

The pop star's sister, Ashlee, gushed about her nephew earlier this month.

"[He's] incredible. He is a doll," she told E! News. "I gotta say he's looking a little like Bronx. They're all little towheads. They're all so cute."

Simpson joked to Ellen DeGeneres in March that both she and fiance Eric Johnson were "extremely shocked" when they found out they were expecting a second child, but were very excited for the new addition.

Still, she said the second pregnancy was not going as smoothly as the first.

"This pregnancy is the complete opposite," she said. "With Maxwell, I felt amazing. I felt like I could do everything, eat everything, do whatever I wanted. I had a lot of energy. This time around I'm exhausted, eating Tums."
