'Lost Change In D Minor' hitmaker will.i.am has stuck his neck out by claiming Justin Bieber has a long career ahead of him.

Talking to MTV about his forth­com­ing musical opus '#willpower', which features a col­lab­or­a­tion with Bieber, the usually long-winded will said: "I like him because he's going to be around for a long time. And he's really talented."

When pressed to describe the col­lab­or­a­tion, he added: "You'll have to hear it."

But when will we be able to hear it will? And who else is going to be on it?

"[I'm a] couple weeks away from com­ple­tion, so we'll have Bieber on the record, Eva Simons on the album, LMFAO, Ne-Yo, a lot of cool folks."

'Cool folks'.
