Justin Bieber and Wife Hailey Announce Arrival of First Baby: 'Welcome Jack Blues Bieber'

Justin Bieber and Hailey Baldwin Bieber are officially parents!

The musician, 30, and his model-entrepreneur wife, 27, have welcomed their first baby together. Justin announced the news on Friday, Aug. 23.

"WELCOME HOME JACK BLUES BIEBER," Justin wrote in an Instagram post. Hailey posted the same photo to her Instagram Stories soon afterwards with the child's name and a teddy bear and blue heart emoji.

Pattie Mallette, Justin's mom, tweeted, "CONGRATULATIONS @justinbieber & Hailey. I LOVE YOU FOREVER BABY JACK!!"

Stephen Baldwin, Hailey's dad, shared Mallette's tweet, adding: "Amen, Congratulations to you and may God continue to bless our family."

The couple first announced they were expecting a child together in May 2024, sharing the exciting news on Instagram. A rep for Hailey confirmed to PEOPLE that the model was just over six months pregnant at the time.

In the video from their vow renewal, Hailey wore a long, lacy white dress and a veil, highlighting her growing bump. She also included a few photos, standing with Justin in a field. With his arms placed around her belly, Justin stood behind her and showed off their matching wedding rings.

The pregnant model kept her caption simple, just tagging her husband.

The couple tied the knot in September 2018 in a New York City courthouse just two months after getting engaged. They later celebrated with a larger ceremony in front of family and friends, exchanging vows and Tiffany wedding bands as the sun set in Bluffton, South Carolina.

In October, Hailey appeared on the cover of GQ Hype and addressed rumors about her being pregnant, commenting on whether they affected her. "Recently, everybody was like, 'Oh my God, she's pregnant,' and that's happened to me multiple times before," she told the outlet.

"There is something that's disheartening about, damn, I can't be bloated one time and not be pregnant? It would be a lie if I was like, 'Oh yeah, I don't give a s---.'"

"When there comes a day that that is true, you, you as in the internet, will be the last to know," she candidly added.

Although she has previously discussed raising her kids out of the spotlight, the model said at the time that she felt it's "probably totally unavoidable."

"That was before I was married. Didn't know who I was going to be married to at the time, I'm sure," she continued.

Despite her trepidations, the model said that motherhood "is something that I look forward to."

"It's also such a private, intimate thing. It's something that's going to come when it comes."

"And it's just, honestly, at the end of the day, so hilarious how much people f---ing care. Let me do what I want with my body and you guys can do what you want to do with your body — and let's just let it be that," she said.

Justin has long said that he wants to start a family with Hailey but noted in a December 2020 appearance on The Ellen DeGeneres Show that he was respecting his wife's timeline.

"I am going to have as many [babies] as Hailey is wishing to push out. I'd love to have myself a little tribe," the "Baby" singer said at the time. "But, yeah, it's her body and whatever she wants to do. ... I think she wants to have a few."
