LOS ANGELES: Pop superstar Justin Bieber on Friday announced the birth of his son – Jack Blues – with his model wife Hailey in a post that quickly garnered millions of likes on Instagram.

“WELCOME HOME JACK BLUES BIEBER,” the singer posted alongside a photo of a baby’s foot wrapped in a blanket, which has racked up more than 5.5 million likes.

The celebrity couple announced in May that they were expecting, posting photos of fashionista and businesswoman Hailey, 27, cradling her baby bump.

Entertainment website TMZ reported Friday that baby Jack was the couple’s first child.

Justin Bieber, 30, burst onto the international scene as a teen pop sensation in 2009, and has since gone on to release hits including the smash hit “Baby,” featuring rapper Ludacris, and “Somebody to Love.”

His army of fans, known as “Beliebers,” helped make him one of the best-selling artists of all time.

Fans were quick to congratulate the duo on Instagram, with one commenting: “I need to play that song ‘Baby’ one more time.”

Hailey Bieber, the daughter of actor Stephen Baldwin, has modeled in campaigns for major brands including Ralph Lauren and Tommy Hilfiger.

She now has her own brand – Rhode – which sells skincare and makeup.
