It looks like Justin Bieber has a new mystery woman.

The 21-year-old left fans guessing on Sunday when he uploaded an Instagram picture of himself standing close to an unknown woman.

“Lord knows,” the singer captioned the photo, which did not reveal the woman’s face, but it did show off her right leg.

Soon, the photo’s comment section was abuzz with fans asking, “Who is it?” (And some even claiming that it was Photoshopped.)

Shortly after posting the photo, the “Sorry” singer took to Instagram once more, uploading a photo of himself with a group of people lounging in a dimly lit room.

“Good times good people good luck,” the singer wrote alongside the snap.

Bieber has yet to explain the cryptic photo or identify the mystery woman. But fans may be able to scratch one prospect off the list: Selena Gomez.

Although Bieber recently shared a slew of throwback photos of his ex on Instagram, a source told PEOPLE that the two are not getting back together any time soon.

“They care about each other and miss each other, but they’re not getting back together right now,” the source said.
