Jessica Simpson debuted her baby son, Ace Knute Johnson, on the cover of this week's Us Weekly magazine. Jessica and her fiancé, Eric Johnson, welcomed their first son on June 30 via planned C-section. The cover was not all about the newborn, though, since new big sister Maxwell, who is 15 months, also posed for the adorable shot with her mom and brother. Of welcoming their newest addition, Jessica gushed, "It's fun! I feel very at peace with being a mom."
While motherhood appears to suit Jessica well, she is not planning to expand her brood anytime soon, which she revealed inside the publication, saying, "Pregnancy is a lot. It was hard to do two so close together. I have this huge sense of accomplishment, and I feel in my heart that I'm done. But obviously, accidents do happen!"
