The married couple announced the exciting news with an adorable snapshot of their new baby boy, Ziggy, on social media over the weekend.
“10-29-2020 Ziggy Blu Ross. Our sweet boy has arrived! I’m over the MOON we are so Blessed!” Simpson captioned the Instagram post on Saturday (Oct. 31).
In the sweet photo, Ziggy is sound asleep while swaddled in brown blanket with both of his parents’ hands resting gently on his chest.
“I’m in heaven,” Ross wrote in a separate post.
Simpson and Ross already share one child together, 5-year-old daughter Jagger Snow. The “Pieces of Me” singer also has an 11-year-old son, Bronx Mowgli, whom she shares with ex-husband Pete Wentz.
