Stephen Baldwin Shares Reaction Over Daughter Hailey Bieber and Justin Bieber’s New Baby

The world just met the teeny-tiny foot of Justin Bieber and Hailey Bieber's newborn son, Jack Blues Bieber.

Less than four months after revealing Hailey's pregnancy, the couple confirmed Aug. 23 that their first child together had arrived. And Jack should be done meeting his massive family at least by the time he's 18.

Hailey and Justin's first child together notably has the J.B. initials of his father and first-time granddad Jeremy Jack Bieber—who seemingly inspired the baby's first name as well.

Justin is Jeremy's only child with ex Pattie Mallette. The 49-year-old is also dad to daughter Jazmyn and son Jaxon (with ex Erin Wagner), and daughter Bay (with wife Chelsey Rebelo) as well as stepdad to Chelsey's daughter Allie. 

Meanwhile, over on his mama's side, Jack is the second grandchild for Stephen Baldwin, 58, and wife Kennya Deodato. Hailey's older sister Alaia Baldwin shares 4-year-old daughter Iris Elle Aranow with husband Andrew Aranow.

"CONGRATULATIONS @justinbieber & Hailey. I LOVE YOU FOREVER BABY JACK," new grandma Pattie wrote on X Aug. 23 after Justin broke the news of Jack's birth (exact DOB TBD).

Stephen reposted the sentiment, adding, "Amen. Congratulations to you and may God continue to bless our family."

Meanwhile, we're guessing your head might already be spinning a bit, what with all these siblings and grandparents. And as far as Hailey's famous family is concerned, we've only just begun.

But we've taken the time to untangle the big Baldwin family tree for you, including Hailey's five paternal aunts and uncles (Stephen is the baby of his generation) and more than two dozen cousins.

And that's not even including Hailey's first cousin Ireland Baldwin's 15-month-old daughter, Holland!

In fact, Ireland—whose parents are Alec Baldwin and Kim Basinger—shared earlier this month that her and partner André Allen "RAC" Anjos's child had "finally met her aunts and uncles," as in Alec's seven children (all currently under the age of 12) with second wife Hilaria Baldwin.

So, we were not joking as far as it taking a minute before all these relatives can get a little face time with new members of the family. 

OK, yes, the tree is getting away from us again. Before this genealogy gets even more complicated, here's a complete guide to Hailey's huge family on the Baldwin side:
