Speaking to Capital FM about the album Will.i.am said, "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."

The musical partnerships don't stop their however. The 'Heartbreaker' singer added, "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."

Further explaining the inspiration for his fourth solo LP Will.i.am said, "#willpower is just a reminder to myself of staying [a] contestant with the dream - keeping the dream alive.

He went on to say. "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."

'Willpower' is set for release later this year.
