Three of the world's biggest stars may just have something very cool in the works.

According to a recent tweet from "Gangnam Style" superstar Psy, he is working on a collaboration with his fellow YG Entertainment label-mate G-Dragon and Canadian pop star Justin Bieber.

On November 26, Psy tweeted the Twitter handles of himself, G-Dragon and Justin Bieber with the hashtag, "#gonnagiveyousomething", indicating that perhaps the three are working on a new project together.

A few days ago G-Dragon confirmed he and Bieber were working on a new track together and that the Canadian singer had already recorded his part of the song.

Additionally, rumors have been flying since Psy signed with Bieber's manager Scooter Braun last year that a collaboration between the two was inevitable.

Speculation was fueled further by Bieber's ambiguous tweets during his recent stay in South Korea for his first concert in the country, when he mentioned working with both Psy and G-Dragon.

Now Psy's latest update seems to confirm that something is definitely going on, which includes all three of them.

The real question now is if the collaboration is a single song between the three talented musicians, or if the G-Dragon-Bieber pairing is separate from the potential one including Psy?

Whatever G-Dragon, Psy, and Justin Bieber have up their sleeves, it's sure to be exciting! Stay tuned for more updates on this collaboration mystery.
