Hailey Bieber and Justin Bieber’s baby boy is actually a Leo.
The couple’s friend Adwoa Abwoa seemingly revealed that Jack Blues Bieber was born Aug. 22 while announcing the birth of her own baby, Shy.
“Our stunner of a daughter was born at 11:22pm on the 23rd of August by emergency cesarean,” Adwoa wrote alongside snapshots of her birth on Instagram Aug. 27. “Our hearts have literally exploded into a million pieces. Shy Trinity Afua Wheatley.”
The Rhode Beauty founder commented six heart-eye emojis and wrote, “Baby Shy!!!!” To which Adwoa replied, “A day apart.” Justin confirmed that he and Hailey welcomed Jack on Instagram Aug. 23 when the 30-year-old posted a photo of their little one’s foot. He captioned the sweet news, “WELCOME HOME.”
Friends and family of the pair couldn’t help but gush over the newest addition to the Bieber family. Justin’s mom, Pattie Mallete, celebrated the news, writing on her Instagram Stories, "Oh my heart. Welcome baby Jack!! I love you so much! Thank you Lord. What a miracle!" Hailey’s dad, Stephen Baldwin, added on X, “Congratulations to you and may God continue to bless our family.”
Meanwhile, Kylie Jenner commented, “I can’t handle this little foot JACK BLUES.” And Khloe Kardashian wrote, "Jack blues!!!!!! Congratulations!!!!! I love this tiny foot so so much."
For Hailey, who announced her pregnancy when she was already six months along, privacy amid her journey was crucial.
“In the beginning, it was super emotional for me,” she told W Magazine in July of spending time with Justin during 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 it wasn’t too difficult to hide her bump for a while, either.
“I was honestly able to keep it quiet because I stayed small for a long time,” she revealed. “I didn’t have a belly, really, until I was six months pregnant, which was when I announced it. I was able to wear big jackets and stuff.”
Eventually, keeping it under wraps became more and more of a hassle, and she ultimately shared the exciting news.
“I probably could have hid it until the end,” the 27-year-old admitted. “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.”
