Stephen Baldwin is once again a grandpa.

After his daughter Hailey Bieber and her husband Justin Bieber welcomed their first baby together, a little boy named Jack Blues Bieber, Stephen—who is also dad to 31-year-old Alaia Baldwin—celebrated his family’s newest arrival.

In response to a message shared to X, formerly Twitter, by Justin’s mother Pattie Mallette which read, “CONGRATULATIONS @justinbieber & Hailey. I LOVE YOU FOREVER BABY JACK,” Stephen wrote on Aug. 23, “Amen. Congratulations to you and may God continue to bless our family.”

Jack’s arrival was confirmed three months after Hailey and Justin first shared they were expecting with the world, when the Rhode beauty founder was already six months into her pregnancy journey. It was a deliberate choice for privacy on their part.

“In the beginning, it was super emotional for me,” Hailey told W Magazine in an interview published July 23 of spending time with Justin amid her pregnancy. “Like, ‘I love this human so much. How can I possibly bring someone else into this?’ I’m trying to soak in these days of it being Justin and me, just the two of us.”
