Justin Bieber showed his pride as a new father in his first post since welcoming son Jack Blues with wife Hailey Bieber in late August.

The Let Me Love You singer, 30 — who ‘wished and prayed’ for his baby boy — took to Instagram to share a carousel of photos including a snap of a mug that read ‘Papa Bear,’ on Tuesday.

The adorable mug displayed a drawn image of a bear in the woods wearing a bowtie and held a heart in his paws.

And his supermodel wife also expressed her excitement as a first-time mother on her Instagram Story.

She rocked a stunning gold ring that read ‘Mom’ in diamond lettering, while also showing off her $1.5million engagement ring.

Justin also added snaps of himself smiling while enjoying a car ride with friends.

He also shared throwback photos of himself wearing a neon pink tie-dye shirt and matching shorts teamed with a white beanie and sneakers.

And the GRAMMY winner didn’t forget his bride of almost five years.

He added a selfie of the Rhode Skin founder that teased half of her face and showed off her plump pout.

We also see the One Time singer don a Stanford sweater and loose jeans in a black and white image.

The Canada native shared a snap of himself sleeping under a red light and an up-close selfie with his eyes closed.

His post was a hit with his 294million followers, racking up over 1.5million likes and thousands of comments from supportive fans.

The singer’s former stylist, Karla Welch, wrote, ‘Papa Bear.’ And his Justice World Tour concert opener Eddie Benjamin shared three red heart emojis.

Justin’s photo dump marks his first post since sharing the surprise via Instagram of his son’s birth on August 23.

Beliebers got a glimpse of the popstar’s baby’s tiny foot and Hailey’s hands.

‘WELCOME HOME JACK BLUES BIEBER,’ the proud dad penned in the caption.

The A-list couple did not clarify the exact day they welcomed little Jack Blues.

And fans have praised the pair for giving him ‘the most normal celebrity baby name in a while.’

We last saw Justin on Friday attending a church service in Beverly Hills for the first time since becoming a first time dad.

The pair tied the knot back in 2018 after almost four years of dating on and off.

They were first introduced in 2011 by Hailey’s father Stephen at the premiere of Justin’s documentary Never Say Never.

Back in May, Justin and Hailey announced they were expecting as they shared snaps of the new New York native flashing her baby bump.
