Justin Bieber and Hailey Baldwin have officially become parents! The couple welcomed their first child, a son named Jack Blues Bieber, on Friday, Aug. 23. The announcement was met with overwhelming joy from fans and family alike, including an emotional reaction from Justin’s mother, Pattie Mallette.

Shortly after the Grammy-winning artist, 30, shared the news on Instagram with a heartwarming photo of his newborn’s tiny foot, Mallette took to her Instagram Stories to express her excitement. In a heartfelt message, she called the arrival of baby Jack a “miracle.”
 

“OH MY HEART,” Mallette, 49, wrote in all caps, overlaying the image of her grandson’s foot. “WELCOME BABY JACK!! I LOVE YOU SO MUCH!😭😭😭🫠🫠🫠🥹🥹🥹.”

Mallette, who is now a first-time grandmother, added, “THANK THE LORD[,] WHAT A MIRACLE! 🎉💃🙌,” showcasing her deep gratitude and joy.

She continued her celebration on X (formerly Twitter), sharing an emoji-filled message of congratulations to Justin and Hailey. “😭😭😭😭😭😭 🥹🥹🥹🫠🫠🫠 🙌🙌🙌🙌🙌🙌 CONGRATULATIONS @justinbieber & Hailey,” she tweeted. “I LOVE YOU FOREVER BABY JACK!!”

Justin, who is Mallette's only son, announced the birth with a simple yet touching Instagram post captioned, “WELCOME HOME JACK BLUES BIEBER.” Hailey, 27, shared the post on her Instagram Stories, adding their son's name alongside a teddy bear and blue heart emoji.

The couple, who tied the knot in September 2018, first revealed they were expecting their first child together in May 2024. Hailey, the model-entrepreneur behind Rhode, was reportedly over six months pregnant at the time of the announcement.

Pattie Mallette has been a vocal supporter of her son’s journey into fatherhood. Back in June, she dedicated a touching Father’s Day post to Justin, expressing her confidence in his ability to be an amazing dad. “You’ve always wanted to be a dad ever since I can remember,” she wrote. “You have so much love to give. You’re gonna be the best daddy ever. You already are. LOVE YOU!! 🥰”

The joy of baby Jack’s arrival has also resonated throughout the Baldwin and Bieber families. Hailey’s father, Stephen Baldwin, shared Mallette’s tweet, adding, “Amen, Congratulations to you and may God continue to bless our family.”

Celebrities and friends, including Tori Kelly, Ice Spice, The Kid LAROI, Tems, Coi Leray, and Chance the Rapper, also sent their best wishes to the new parents by commenting on Justin's announcement post.
