Nick took to his Instagram on Monday night (August 8) to share a blurry photo of the pair goofing off together.
“Flashback @justinbieber,” Nick captioned the image, adding in a praise hands emoji.
We can’t tell exactly when the photo is from but Justin‘s hair looks a lot longer and a lot more blonde so it’s probably not from this summer.
We’d still love to know what the duo did together! Did they talk about their mutual ex Selena Gomez? Work on new music? Only time will tell!
