Since the birth of their son Jack, Justin and Hailey Bieber have been in "baby bliss."

The announcement of the birth of their first child, a baby named Jack Blues Bieber, was made by Hailey and Justin Bieber on August 23. The announcement was accompanied by a picture of the newborn's foot wrapped in a blanket and a picture of Hailey's immaculate manicure, with the text "WELCOME HOME."

As a family of three, the couple's first few days together have been described as "a magical experience," an unnamed source told Star Magazine.

“Justin has been doting on little Jack nonstop, changing diapers and singing lullabies. Hailey’s exhausted but Justin’s encouraging her to sleep and is right by their side 24/7,” the anonymous insider went on.

The pop diva and beauty mogul, who tied the knot in 2018, waited for a period of six years before beginning a family, although they have been public about their desire to have children for many years. Shortly after the couple tied the knot, Hailey, who is 27 years old, disclosed, "I love kids and I can't wait to have my own."

They were still very much thinking about having children two years later, with Justin, who was thirty years old at the time, revealing, " I am going to have as many as Hailey is wishing to push out... I’d love to have myself a little tribe.”

Hailey confessed that pregnancy was not always easy for her, stating that she experienced morning sickness that lasted throughout the entire day but that she enjoyed satisfying her cravings for pizza.

"On cloud nine" is how the power couple describes their feelings after finally becoming parents, according to the undisclosed informant.

“They’re not letting a ton of people come over yet, but Justin’s been FaceTiming everyone and bragging about how amazing Jack is. He’s a very proud new dad and already seems to have grown up thanks to this new responsibility. He’s really thrown himself into parenthood. He and Hailey are both so in love with Jack. It’s getting better with each passing minute,” the tipster shared.

Moles, close to the couple, told PEOPLE Magazine a few days after the baby was born that they were "both overjoyed" and that the kid was "adorable" and "such a miracle" for the couple. In addition, the spy disclosed that both Jack Blues and Hailey were in good health and operating normally.

"The pregnancy was something that they very much wished and prayed for. The day they found out that Hailey was pregnant was the best ever for Justin. He was over the moon with excitement. It was a big celebration for them,” the tattler said. It added that “Justin's already a great dad.”

Pattie Mallette, Justin's mother, had already expressed the same attitude on Instagram many months earlier when she was celebrating Father's Day in June this year. “Happy Father’s Day, Justin. You’ve always wanted to be a dad ever since I can remember. You have so much love to give. You’re gonna be the best daddy ever. You already are,” she penned.
