Justin Bieber has shown off what appears to be a tiny new tattoo on his face.

The Canadian hitmaker posted a 'selfie' on Instagram.com ahead of his concert in Philadelphia, Pennsylvania on Saturday (07May16), when he displayed a small black mark next to his right eye.

"Resting up for the show in Philly it's gonna be a good one mark my words," the 22-year-old captioned the shot, not addressing the apparent new ink on his face.

Fans were quick to assume that the mark was a new piece of skin art, and celebrity tattoo artist Jonboy, from New York City shop West 4 Tattoo, seemingly confirmed it was real by sharing a photo of Bieber sporting the dark ink, along with a curiously red and swollen cheek.

Bieber has yet to comment on the tattoo, but back in February (16), he told GQ magazine he would only consider getting a face tattoo when he's older.

"Maybe when I'm really old, not super old, but maybe, like, 40s or 50s or something," Justin explained. "One above my eyebrow or something small. I think if they're done right, they could be cool, but nothing super crazy all over the face."
