Top celebrity tattoo artist Bang Bang has revealed to “Page Six TV” that Justin Bieber has a new face tattoo — but the singer has not revealed it yet publicly.

The facial ink was part of a couples’ tattoo he did for Bieber and his rumored new wife, Hailey Baldwin. But Bang Bang, a k a Keith McCurdy, is staying mum on the tattoos’ significance or placement.

“They each got a tattoo,” said McCurdy. “Justin’s tattoo is on his face, and I haven’t seen any photos of it — so he’s doing a good job of laying low.”

The ink pro added, “It’s really thin and delicate. And [it’s] also not a traditional couples’ tattoo . . . I don’t want to give away what it is until press gets a hold of it.”

But McCurdy did reveal that Bieber’s tat was next to his eyebrow and includes “little words.”

There have been some hints about the couples’ ink. After McCurdy’s interview, we noticed Bieber was photographed in July with some possible facial art around his eyebrow that seemingly reads “Grace.”

Tattoo artist JonBoy — who was responsible for Bieber’s first face tattoo, also nearly invisible — posted a photo of the couple and captioned it “Style&Grace.”

McCurdy’s also the go-to artist for celebrities Selena Gomez, Demi Lovato, Adele and Rihanna.

“I’ve done some tattoos on celebrities in really painful spots. I’ve made Rihanna cry,” he told “Page Six TV,” “because it’s been so painful on certain body parts.” He added of the tearful tat, “It was the tattoo on her ankle area, the Egyptian falcon. I think just being tattooed on your foot. She was not feeling it — but she thugged up,” he said.

McCurdy started working with the “Umbrella” singer over a decade ago.

He told Page Six Style of couples getting tattooed together like Bieber and Baldwin: “I don’t know if more couples are doing it now, but I do think the media’s taking more notice. Now they’ll get these tattoos, and there’ll be 1,000 articles about them . . . People are really curious about these tattoos and their meanings.”
