Justin and Hailey Bieber have confirmed the arrival of their first child

He captioned the picture: "WELCOME HOME. JACK BLUES BIEBER."

The Rhode Skin founder and the 'Sorry' hitmaker announced in early May that they were expecting a child - and revealed Hailey was six months along at the time, making her due date sometime in early August.

Hailey didn't announce their big news until she was six months pregnant as she was able to hide her small bump using "big jackets".

She told W magazine: "I was honestly able to keep it quiet because I stayed small for a long time. 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."

Hailey went on to admit she "probably could have" kept the pregnancy a secret all the way through to the birth, but she didn't like keeping such big news quiet.

She added: "I probably could have hid it until the end. 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."

Hailey had hoped she could raise a child away from spotlight - but that all changed when she married Justin in 2018.

She previously told GQ: "It's probably totally unavoidable. That was before I was married. Didn't know who I was going to be married to at the time, I'm sure.

"Maybe I liked the idea at 18 of not raising kids around certain things, but my life is so different now than it was when I was 18."
