*Will.i.am’s “#willpower” album will have some serious star power.

In addition to Jennifer Lopez and Mick Jagger, who join the Black Eyed Peas frontman on lead single “T.H.E. (The Hardest Ever),” Will.i.am told Capital FM that musicians including Britney Spears, LMFAO, Alicia Keys, Swedish House Mafia and Shakira will be among the album’s contributors.

“I have a song with Alicia Keys – me, Alicia and Swedish House Mafia. I have a song with The Beats, which is pretty grand. Me and Shakira have been trying to finish the stuff we started, and me and Britney is really crazy,” he tells Billboard.com. “We got a song with me, LFMAO and Eva Simons. A song with me and Busta Rhymes and Swizz Beats. I got a whole other bunch of collaborations.”

Will.i.am promises an “uplifting” album that will provide “encouragement for those who need it.”

“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,” he explained, hoping he can share the inspiration.

However, fans of the rapper-producer may be surprised with one of his upcoming efforts.

“I made this song with Nicole Scherzinger that you never expect,” he added. “It’s classical music.”

A release date for “#willpower” has yet to be announced. “T.H.E. (The Hardest Ever)” will see an official release on Feb. 5.
