What's next for Justin Bieber? Well, if 'Gangnam Style' star Psy is to be believed, the teen star will be teaming up with him for an upcoming single release.

When speaking to Capital FM, Psy told the radio station that he has been planning a collaboration with the young star, although they haven't yet finalised any of the details.

Psy said: "Yeah, so we have a plan to do something together later but we doesn't have any details yet. But, sure - we gonna do some work later on."

He promised that the collaboration would definitely be a hit, pointing out that the pair's combined star power would lead to millions of hits on YouTube. He continued, "I mean of course you know, hundreds of millions [of views] combined on YouTube - it's gonna explode right?"

Psy previously teased the collaboration at the MTV Europe Awards, according to The Sun, although he wouldn't then confirm that it was with Bieber.

When asked about the possibility of the two working together, he said, "So, I already have done with the next track already. I cannot tell you about who it's gonna be with but I'm working with someone else right now and it's going to be huge.

"I'm working on my next album and single, and it has more English so you can get it. I feel happy and sorry because when I perform the song they look so happy, but they don't have any idea what I'm talking about.

"So we're gonna have some English in it."

Both Psy and Justin Bieber share Scooter Braun as their manager.
