Justin and Hailey Bieber have the best intentions for their newborn baby boy.

The Holy hitmaker, 30, is ‘already a great dad’ — since welcoming son Jack Blues — and overjoyed to be a father according to a source close to him and wife Hailey, 27.

And parents is something the A-list couple had dreamed of for years.

‘The pregnancy was something that they very much wished and prayed for. The day they found out that Hailey was pregnant, was the best ever for Justin,’ an insider told People.

‘He was over the moon with excitement. It was a big celebration for them,’ the source revealed to the outlet.

The source emphasized that the GRAMMY winner and the model were overjoyed to become first time parents and navigate the world as a party-of-three.

‘The baby is such a miracle. He’s adorable and doing well. Hailey’s doing well too,’ the source said of the little bundle of joy and his mother.

Justin announced his son Jack Blues’ birth in a surprise Instagram post on Friday after wife Hailey had gone AWOL since late July.

Beliebers got a glimpse of the popstar’s baby’s tiny foot and Hailey’s hands.

‘WELCOME HOME JACK BLUES BIEBER,’ the proud dad penned in the caption.

The former Victoria’s Secret model shared the post on her Instagram Story with the youngster’s name and various emojis.

Although they did not clarify their son’s date of birth, his name holds special meaning to the Canadian superstar.

The ‘JB’ initials read along the lines of tradition for the Bieber clan staring off with Justin’s dad, Jeremy Jack Bieber, the Holy singer himself and his youngest siblings Jaxon and Jazmyn Bieber.

The new parents have yet to confirm that their son’s name is a nod to Justin’s dad’s middle name.

Pattie Mallette, the Purpose singer’s mother, took to X (formerly Twitter) to celebrate becoming a grandmother at 49. She wrote: ‘CONGRATULATIONS @justinbieber & Hailey. I LOVE YOU FOREVER BABY JACK!!’

Stephen Baldwin, Hailey’s dad, reshared the sweet note, writing, ‘Amen, Congratulations to you and may God continue to bless our family.’

The pair tied the knot back in 2018 after almost four years of dating on and off.

They were first introduced in 2011 by Hailey’s father Stephen at the premiere of Justin’s documentary Never Say Never.

Back in May, Justin and Hailey announced they were expecting as they shared snaps of the new New York native flashing her baby bump.
