KJ Apa is 'getting married'?!

KJ Apa has broken "a billion hearts" after announcing he's getting married.

But don't hold your breath, it looks like he was only kidding - the Riverdale star cracked the joke after accidentally wearing the same outfit as his friend and fellow music enthusiast, Paul Mabury.

The actor posted a pic of the pair holding hands and laughing, saying: "We're getting married!"

Fans have commented on the snap saying "congrats" and "a billion hearts break."

While wedding bells may be off the cards, it seems KJ might be making music with Paul, who is an award-winning producer, a professional drummer and a co-owner of a sample company called That Sound.

Paul posted a similar pic of the pair with the caption: "When the 'artist' ( @kjapa ) & the 'producer' accidentally wear the same thing".

He also joked: "It's all good... as you can see, we don't like working together!"

It'll be awesome to see what the pair come up with!
