Will.i.am has revealed that producing U2's new album has been a milestone in his career.

The Black Eyed Peas frontman is lined up to produce the band's next album along with Dangermouse.

"You talk about one day looking back at milestones in your career - working with those guys will be light-year stones. I look at U2 and think, 'Wow, I hope our group can stay together that long and still make brilliant music," Will.i.am told The Sun.

He added: "I went to Bono's house for lunch and George Clooney and Cindy Crawford were there. I played some of the songs we'd been working on together and everyone was blown away. They all left the finger food to come and hear."

Meanwhile, The Black Eyed Peas new album 'The Beginning' was released last Tuesday (November 30).
