Although this is the first photo of her son that she’s posted since announcing his birth, Hailey has alluded to her little boy with several new pieces of jewelry.

In a video posted to her TikTok earlier in October, Hailey shared her routine as she got ready for the day. The newly minted mom could be seen using some of her brand’s products and as she put on her skincare, showing off a new gold bracelet on her arm.

The gold band subtly appeared on her arm in between a gold watch and another gold band and read “Jack Blues” written across the front.

She also posted a photo on Instagram that same month and her photo dump included a pic of a gold chain with “JBB” arranged in bubbly letter pendants, encrusted with gemstones.

Justin revealed in a sweet Instagram post in August that his wife had given birth to baby Jack.

“WELCOME HOME JACK BLUES BIEBER,” he wrote alongside a black and white photo of the newborn’s tiny foot. The model re-shared the photo to her Instagram Stories soon after, captioning it with the baby’s name as well as a teddy bear and blue heart emoji.

The family tradition of naming their son with the initials ‘JB’ has continued on Bieber’s side of the family for a couple of generations now, as the singer has the same initials, along with his dad, Jeremy Bieber, and some of his siblings.

After the couple welcomed their baby, a source told PEOPLE that Bieber is “already a great dad.”

“The pregnancy was something that they very much wished and prayed for. The day they found out that Hailey was pregnant, was the best ever for Justin,” the source said.

“He was over the moon with excitement. It was a big celebration for them,” they added.

The source also said the pair are “both overjoyed” after welcoming the little one, telling PEOPLE, “The baby is such a miracle. He’s adorable and doing well. Hailey’s doing well too.”
