will.i.am is adding some star power to his upcoming album. The Black Eyed Peas frontman has enlisted Alicia Keys, Britney Spears, Nicole Scherzinger, Busta Rhymes, Shakira, and more for #willpower.

The fourth solo project from the platinum hitmaker is due later this year. “#willpower is just a reminder to myself of staying consistent with the dream—keeping the dream alive,” will told Capital FM.

“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 uplifiting songs, encouragement for those that need it.”

In addition to Jennifer Lopez and Mick Jagger on the first single “T.H.E (The Hardest Ever),” will has populated the project with superstar guests. “I have a song with Alicia Keys—me, Alicia, and Swedish House Mafia,” he shared. “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.”

But that’s not all. “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.”

He has also recorded a “classical” record with Nicole Scherzinger. “I made this song with Nicole Scherzinger that you would never expect,” he explained. “This classic piece of music that I did with Nicole, it’s beautiful. That girl sings like I’ve never heard anybody sing like that in pop culture. She is thebomb.com/isthatnicole?”

Last year, the Black Eyed Peas announced that they would be taking a hiatus. In addition to readying his star-studded album, will has been in the studio with Chris Brown and Justin Bieber.
