Jessica Simpson’s son is four years old!
The singer and fashion designer took to Instagram to mark the occasion, sharing a video of Ace and his sister, Maxwell, 5, singing “Happy Birthday”.
Simpson later continued the festivities, sharing a shot of a grinning Ace flanked by balloons and a massive birthday cake.
While the former “Newlyweds” star, who is married to former NFL player Eric Johnson, is clearly a devoted mom, she recently told Ellen DeGeneres she has no plans to expand her family after getting an IUD. “I have two beautiful children, and I’m not having a third,” she declared.
