'U Smile' hitmaker Justin Bieber seems to have formed a '#SUPERGROUP" with Adam Levine and Ryan Tedder.

Last night he tweeted: "long night in the studio. good seeing big [email protected] — we got a big idea coming!#newSupergroup.”

Bieber then posted earlier today: “big night in the studio tonight. glad to add my boy ryan [email protected] to our #SUPERGROUP.”

The singer also included bodyguard Kenny Hamilton in tweets referring to the proposed super­group but it’s not clear if his role is musical.

Bieber’s new single 'Boyfriend', produced by Mike Posner, will debut in at the end of this month.
