Jack Blues Bieber is already sporting custom jewelry.

Over the weekend, Hailey Bieber showed off her 10-month-old son, Jack Blues, wearing a personalized Alison Lou bracelet.

Jack rocked the label’s teeny-tiny baby enamel ID bracelet ($685), which was engraved with his initials — JBB — in all black.

Though she didn’t include the baby’s face, the Rhode founder, 28, shared an image of the infant with the gold chain bracelet while gripping onto the wall of his playpen. 

Justin, 31, also posted the couple’s first child with the custom jewelry. In his Instagram image, Jack Blues wears a royal blue T-shirt as his tiny hand grips white slippers from the “Baby” hitmaker’s forthcoming fashion brand, SKYLRK.

“THE LIL JBB BRACELET 🥹🥹 MY HEART,” one person gushed in the comment section. “His cute bracelet!!! ❤️❤️❤️❤️,” another wrote.

The beauty entrepreneur has quite a collection of custom jewelry that pays homage to her son. Last October, she debuted a blinged-out necklace featuring his initials in bubble letters.

She also has a diamond-covered “Mom” ring, a toi et moi ring featuring both her and Jack’s birthstones, and a bracelet with his name written in gothic letters.

Justin has gotten in on matching with his son, too, designing a tiny bathrobe and matching beanie for his mini-me.

The sweet moments came on Father’s Day, which saw Justin posting a slew of concerning messages alongside those of his family.

After getting into a screaming match with paparazzi on Friday, he declared “I’m a dad that’s not to be f—ked with” and included a middle finger emoji, echoing his rant from earlier in the weekend.

Hailey co-signed the message, dropping a “like” on the post, though she later sent a shady message, writing “Father’s Day sucks ass” on one of his many posts, calling back to when he said the same on Mother’s Day.
