Stephen Baldwin is celebrating the birth of his daughter Hailey Bieber‘s first child.

The actor and film producer, 58, took to social media to congratulate the model, 27, and her husband Justin Bieber, 30, on becoming new parents after their birth announcement.

After the Peaches hitmaker announced that they welcomed a baby boy named Jack Blues Bieber on Friday, his mother Pattie Mallette, 49, shared her excitement on becoming a grandmother with sweet posts on Instagram and X, which Baldwin reposted.

Alongside a series of teary-eyed emojis, she wrote on X: ‘CONGRATULATIONS @justinbieber & Hailey. I LOVE YOU FOREVER BABY JACK!!’

In response to her tweet, Baldwin reposted and penned a message back to Mallette and their kids.

‘Amen,’ he wrote with the prayer hands emoji. ‘Congratulations to you and may God continue to bless our family.’

His congratulatory message shared via social media comes after Hailey admitted that she’s not as close to her family as she used to be.

‘I’m not super close with my family at this point in my life,’ she told W Magazine in her cover story for the special summer issue. ‘Because I feel like I’m very independent.’

‘I’m my own individual now, and I’ve built my own family. But when I look back on my childhood and how I grew up, I have very fond, beautiful memories.’

She said the distance stemmed from her moving out of their family home as a teenager to pursue her modeling career, which forced her to grow up faster.

She recalled signing with a modeling agency, Ford Models, at 17 and packing her bags to for her move to New York City.

‘I started traveling the world, making my own money. I got my own apartment and had to learn how to live on my own,’ she said. ‘That pushed me into adulthood kind of quickly.’

And for her even earlier childhood years, she recalled having a ‘normal’ childhood, as normal as it could be being a part of a famous family at least.

‘I had a fairly normal childhood. Obviously, I come from the family that I come from, and I always recognized that that was different,’ she said with measured self-awareness.

For her cover story, she showed off her baby bump during the shoot and spoke about her pregnancy announcement.

The couple — who have been married since September 2018 — made the exciting revelation when they posted a video of themselves renewing their wedding vows in May.

At the time, Hailey’s dad Stephen left a comment underneath their post.

‘Love you guys,’ he wrote to his daughter and Justin. ‘Blessed beyond words, praise God, let’s get ready to have some fun y’all.’

However, in her W cover story, Hailey made it clear that she was only focusing on herself and her husband during her pregnancy — prior to giving birth on Friday.

‘In the beginning [of pregnancy], it was super emotional for me,’ she told the outlet. ‘Like, “I love this human so much. How can I possibly bring someone else into this?”‘

She added: ‘I’m trying to soak in these days of it being Justin and me, just the two of us.’
