will.i.am records with Britney Spears and Shakira

will.i.am is set to thrill fans with superstar collaborations on his new solo album after teaming up with Britney Spears and Shakira.

The Black Eyed Peas frontman has also recruited Alicia Keys, LMFAO and Busta Rhymes for #willpower, which is due for release later this year (12).

Sir Mick Jagger and Jennifer Lopez also contributed vocals to T.H.E. (The Hardest Ever), the first single off #willpower.

Discussing the project, will.i.am tells U.K. radio station Capital FM, "I have a song with Alicia Keys - me, Alicia and (house music group) Swedish House Mafia.

"Me and Shakira have been trying to finish the stuff we started, and me and Britney is really crazy.

"So we got a song with me, LMFAO and Eva Simons. A song with me and Busta Rhymes and Swizz Beatz. I got a whole other bunch of collaborations."

The hip-hop star insists the star-studded disc is a dream come true, adding, "#willpower is just a reminder to myself of staying (a) contestant with the dream - keeping the dream alive. It was all a dream when I was 15 years old - 20 years later I managed to take the dream from an idea to physicality. So #willpower is uplifting songs, encouragement for those that need it."
