The producer is currently working with the singer on her anticipated new album 'Femme Fatale'.

"I just came from the studio right now. It's a monster," Will.i.am told The Associated Press.

He added: "It's mean, pretty, edgy, next level. But the beat just... It's that beat. She's singing fresh over it. It's something that today needs."

The album, released March 29, includes production from her long-time partners Dr. Luke and Max Martin, as well as Rodney Jerkins, Stargate, Fraser T. Smith and Bloodshy & Avant.

Meanwhile, Spears' manager denied reports that the star is due to perform 'Hold It Against Me' at the Grammy Awards this weekend.
