He captioned the adorable post: "Happy Valentine's Day Cheryl and everyone. looks like I've got the big guy to compete with now."
So cute! The only other photo of Bear was shared by Cheryl after his birth.

"Although he still doesn't have a name he is already stealing hearts. We are all madly in love and overwhelmingly happy with our little arrival. Happy Mother's Day to all the mothers around the world. A day that now has a different meaning to me forever 💙"
