Stephen Baldwin is once again a grandpa.

After his daughter Hailey Bieber and her husband Justin Bieber welcomed their first baby together, a little boy named Jack Blues Bieber, Stephen—who is also dad to 31-year-old Alaia Baldwin—celebrated his family’s newest arrival.

In response to a message shared to X, formerly Twitter, by Justin’s mother Pattie Mallette which read, “CONGRATULATIONS @justinbieber & Hailey. I LOVE YOU FOREVER BABY JACK,” Stephen wrote on Aug. 23, “Amen. Congratulations to you and may God continue to bless our family.”

Jack’s arrival was confirmed three months after Hailey and Justin first shared they were expecting with the world, when the Rhode beauty founder was already six months into her pregnancy journey. It was a deliberate choice for privacy on their part.

“In the beginning, it was super emotional for me,” Hailey told W Magazine in an interview published July 23 of spending time with Justin amid her pregnancy. “Like, ‘I love this human so much. How can I possibly bring someone else into this?’ I’m trying to soak in these days of it being Justin and me, just the two of us.”

And while noting keeping the news private was easy because she “stayed small for a long time,” Hailey added, “I probably could have hid it until the end, but I didn’t enjoy the stress of not being able to enjoy my pregnancy outwardly. I felt like I was hiding this big secret, and it didn’t feel good. I wanted the freedom to go out and live my life.”

And now that they’ve welcomed Jack—who seems to be named in tribute to Justin’s dad Jeremy Jack Bieber—Hailey and the “Baby” singer are sharing the happy news with the world. On Aug. 23, the pair shared a photo of Jack’s foot, which Justin captioned, "WELCOME HOME."

And it’s safe to say Stephen wasn’t the only one among the couple’s friends and family who were thrilled by the news.

As Kylie Jenner commented on the couple’s post, "I can’t handle this little foot JACK BLUES," while her sister Khloe Kardashian added, “Jack blues!!!!!! Congratulations!!!!! I love this tiny foot so so much."

Marvel star Chris Pratt—who shares 12-year-old son Jack with ex Anna Farris and daughters Lyla and Eloise with wife Katherine Schwarzenegger—also wrote, “Congrats guys!!! Love the name!!!"

Because as the now-Grandma Pattie noted amid Hailey and Justin’s pregnancy announcement, “you are gonna be the best parents ever, and I am so excited."

So committed to spending my life getting to know every single part of you loving you patiently and kindly," he captioned this photo. "My heart is COMPLETELY and FULLY YOURS and I will ALWAYS put you first," he continued. "You are the love of my life Hailey Baldwin and I wouldn't want to spend it with anybody else. You make me so much better and we compliment each other so well!! Can't wait for the best season of life yet!"

"My lips get jealous of my arms cuz I can hold you with them," Justin shared. We're pretty jealous too! 

Could these two be any cuter?! "My only bubba," Hailey shared about the sweet pic. 

It may be cold outside, but they know how to keep each other warm.

Once again, these two are absolutely slaying the relationship goals! "Go best friend that's my best friend," Justin captioned the pic. 

The couple who prays together, stays together. "I know for me this conference came at the exact time I needed it, I believe God is THAT amazing and faithful that he brings us the right words during the season that we need it the most," Hailey captioned the shot with her hubby.

Amazing views for the gram. The sunset is also pretty nice! 

One of their first official shots as husband and wife! 

Even in this photo taken years ago, this pair was picture-perfect.

In January 2016, the two decided they weren't going to hide their romance any longer, and this photo of them kissing quickly circulated throughout the internet.

Hailey decided to lend a helping hand in January 2015 when she gave Justin her hair-tie right off her wrist!

They might not have been together when this photo was taken in June 2015, but they sure did look good together!

In this photo from May 2015, the "Baby" singer rocked a fake mustache while the model sweetly posed behind him.

In December 2014, Kendall Jenner joined Justin and Hailey for a Nerf gun night!

Earlier in December, the A-lister took to Instagram to shut down any dating speculation between him and Hailey. "People are crazy. I'm super single and this is my good friend u would know otherwise," he wrote. Hmmmmm. Foreshadowing much?
