Justin Bieber and Hailey Bieber have a new somebody to love. The "Peaches" singer and Rhode Beauty founder welcomed their first child together , a baby named Jack Blues Bieber , Justin confirmed on Instagram on Aug. 23 .

The 30-year-old shared the news, writing, "WELCOME HOME," while Hailey also celebrated by reposting Justin's photo to her Instagram Story with a blue heart. And baby Jack's name seemingly pays tribute to someone very special in the couple's lives, as "Jack" is the middle name of Justin's father: Jeremy Jack Bieber . Jack Blues Bieber also continues Justin's family tradition of having "JB" as their initials, with the "Sorry" singer's half-siblings Jazmyn Bieber , 16, and Jaxon Bieber , 14—whom Jeremy shares with ex Erin Wagner —also fitting the "JB" bill.

Justin and Hailey— who tied the knot in 2018 —first announced they were expecting in May , sharing photos and videos to their Instagram accounts that showcased not only Hailey's baby bump but also their sweet vow renewal in Hawaii. And Hailey had a very specific reason for choosing to keep her pregnancy under wraps until her second trimester. "I was honestly able to keep it quiet because I stayed small for a long time," she told W Magazine in July .

"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." And while she thinks she "probably could have hid it until the end," the 27-year-old wanted the joy of celebrating he.
