BLACK EYED PEAS star WILL.I.AM is paying Justin Timberlake back after the singer helped the R+B group score their break-out international hit by producing tracks on his new album.

After lending his voice to 2003 smash-hit WHERE IS THE LOVE? Timberlake has teamed up with the Black Eyed Peas leader again for tracks on his second solo album.

Will.I.Am tells MTV News, "I love working with that dude. It's fun. It's like we're not even working. It's like, 'How did that song come out of nowhere?' There's no ego in the room."

The pair have already completed four new tracks, and the Black Eyed Peas star insists Timberlake's new album is going to be a big hit.

He adds, "He's pushing boundaries once again. It's fresh. It's a different direction, but, at the same time, it's his persona and voice, it's still Justin Timberlake.

"Rhythmically and sonically it's all new stuff, but it's still gonna make you dance. Chicks are gonna love it. That's what's important."
