Justin Bieber’s dad has wholesome reaction to singer becoming a parent for the first time and honouring family tradition

While fans are over the moon for new parents Justin and Hailey Bieber, it seems no one is more thrilled than their own family.

The couple announced the birth of little baby Jack Blues Bieber on Friday (, with Justin posting a sweet snap of Hailey cradling their son’s foot.

"WELCOME HOME, JACK BLUES BIEBER,” he wrote, prompting internet sleuths to immediately set about working out the meaning behind the adorable name, with many speculating that ‘Jack’ was a nod to his dad.

"Jack Blues Bieber Jack is from Justin's dad," one tweeted, adding: "And Blues is because he is a boy, I guess, BIEBER."

Someone else said: "BABY BIEBER IS HERE, AND IT’S A BOY!! I’m guessing he was named after his grandfather, since Jeremy’s middle name is Jack. I’M SOOOOOOO HAPPY!! They’re going to be the BEST parents!!"

PEOPLE also reported that the name seems to follow a family pattern: along with Jeremy Bieber - who split from Justin's mum Pattie Mallette not long after their son was born - there’s also Justin’s half-sister Jazmyn Bieber, 16, and half-brother Jaxon Bieber, 14.

Notice how they all share the same initials, JB, as both Justin and now also his child?

New grandfather Jeremy was clearly overjoyed with the new arrival, having posted a poignant one-word response on X.

“Papa,” he said, as a reference to his son’s new title.

Justin’s mum, meanwhile, was a little less restrained.

"OH MY HEART," the 49-year-old wrote as she shared Justin's announcement.

"WELCOME BABY JACK!! I LOVE YOU SO MUCH! THANK THE LORD WHAT A MIRACLE!”

In another excited post on X, Pattie shared a series of emojis and said: “CONGRATULATIONS @justinbieber & Hailey.

"I LOVE YOU FOREVER BABY JACK!!"

Justin's mum Pattie was also clearly excited (X)

Hailey’s dad, actor Stephen Baldwin, also shared Pattie’s tweet, saying in his own statement: "Amen, Congratulations to you and may God continue to bless our family."

While the A-lister extended family has been very public in their congratulations, Hailey has previously discussed her desire to raise her family out fo the spotlight – something her own parents did.

However, she’s accepted that the attention is ‘probably totally unavoidable’.

“That was before I was married,” the Rhode founder told GQ. “Didn’t know who I was going to be married to at the time, I’m sure.

“Maybe I liked the idea at 18 of not raising kids around certain things, but my life is so different now than it was when I was 18.

“It’s so hard to say what I’m going to do or not do when there isn’t even a child here yet. I don’t even know what it feels like to be a parent other than a dog parent yet.

"And that’s not the same thing, by any means.”
