Justin and Hailey Bieber welcomed their first child.

It was in May this year when Hailey announced that she is pregnant with her first child with Justin. They also renewed their vows in the same month.  

The couple first tied the knot in September 2018 in New York in a courthouse. They had a second wedding in 2019 in a bigger ceremony in South Carolina.

"They were thrilled to have their families and friends in South Carolina. It meant more than they imagined. It was all very special. Although they were already married, their religious wedding ceremony was very important," a source said as reported previously by PEOPLE.

In an interview with Elle Magazine in April 2021, Hailey relayed that she shared the same aspiration with Justin when it comes to having a family young.

"We always knew that we were aligned on what we wanted in our future. We had talked about wanting to be married young and having a family young and building a life. Even before we knew we wanted to be with each other," she stated.
