Justin Bieber has hinted that he could be set to join Adam Levine in a new supergroup.

In a series of tweets posted this morning (March 13), Bieber suggested that he had been in the studio with Maroon 5's Adam Levine.

He confirmed that the pair have a "big idea coming" - and finished off the tweet with the hashtag "new supergroup".

His tweet read: "Long night in the studio. good seeing big bro @adamlevine - we got a big idea coming! #newSupergroup." He then tweeted: "I dont think the world is ready for this #SUPERGROUP."

As previously reported, Bieber's manager Scooter Braun had recently stoked up the flames of teenage girls' hearts around the world by suggesting that a collaboration between the Canadian superstar and Brit boyband One Direction was possible.
