'Riverdale' Star KJ Apa Has a Chronic Instagram Photobomber

Riverdale star KJ Apa absolutely fell in love with Paris this past week. He also took to Instagram to document his travels, highlighting one, uh, photo-bomber in particular.

A shaggy blonde guy is skulking around in all of KJ‘s recent Instagrams, popping in the back of photos and staring at the camera behind groups of fans posing.

Thankfully, we don’t have a code red Blossom twins mystery on our hands. Said stalker in question is his friend, Nick Voroshine, and it is 100 percent an inside joke.

There are now fan accounts for Nick, MTV reports, though some strongly suspect KJ himself runs them.

We can’t lie: the pictures are super funny.

Go inside to see more “stalker” pics.

Here’s proof that they’re friends after all.
