Celebrity Friends, Family React After Hailey and Justin Bieber Announce Pregnancy

The 30-year-old musician took to Instagram to make the announcement, tagging his wife, Hailey in the caption. While Hailey posted the same series of photos, and also kept the caption simple by just tagging her husband.

The carousel started with a super 8mm film of the pair appearing to renew their vows as Hailey is dressed in a white off the shoulder lace gown and matching veil. The images show the Rhode creator cradling her belly as Justin takes photos of her in a field.

Grandfather-to-be Stephen Baldwin, Hailey's dad, shared his excitement about his daughter's pregnancy. The 57-year-old shared a grab of the couple kissing from the announcement clip with a Bible verse written over it, "God is love. Whoever lives in love lives in God, and God in them."

"Love you guys ❤️ blessed beyond words🙏🏼 praise God 👶🏼let's get ready to have some fun y'all 🎉," he wrote in his caption.

Justin's mom Pattie Mallette joined in on Stephen's excitement, commenting on Stephen's post, "Congratulations Grandpa! WE ARE GONNA HAVE THE CUTEST GRAND-BABIES EVER!"

Some eager eyed fans read into Mallette's use of the term "grand-babies" as an accidental slip that the pair were expecting twins. However, the 49-year-old quickly clarified.

"No not twins lol I wish. I just mean in general. Hopefully they will have more than one eventually. They will make beautiful babies whenever they have them. One is enough for now 😂," Mallette wrote on Baldwin's post.

She also posted a video to her own IG page, saying, "So, I have been waiting for this day, and now that they have shared it, I can finally celebrate with y'all and say: Oh my gosh! I'm gonna be a grandma! Oh my goodness!"

"My heart is so full. What an exciting new adventure. Love you so much!" Mallette captioned her video.

Hailey's post has been liked by countless fans and fellow famous friends, including Kim Kardashian, Kendall Jenner and Jen Atkin, while the comment section was flooded with messages of congratulations.

"ahhhh here come the tears again ❤️," Jenner, Hailey's best friend wrote.

While also pregnant Sophia Grainge commented on Hailey's post, "Ahh!! Congratulations 🥹💕😍"

"I love you guys sooooo much!!!!" Kardashian commented, as new mom Paris Hilton wrote: "🥰Congratulations love🩷🩷🩷"

TMZ reports the 27-year-old is six months along in her pregnancy, meaning she will be expecting late summer.

There have been rumors about the pair expecting for a while now, with photos surfacing of Hailey wearing a flowy dress in Hawaii in April, leading many fans to think she was hiding a possible pregnancy.

The couple tied the knot in September 2018 in a New York City courthouse just two months after getting engaged. They later celebrated with a larger ceremony in front of family and friends in Bluffton, South Carolina.
