Will.i.am is teaming up with Britney Spears again.

Britney appeared on the producer and rapper's huge track 'Scream and Shout' earlier this year, and he is set to return the favour, by working on some tracks for her next album.

After hearing will.i.am's new song '#THATPOWER' with Justin Bieber, Britney tweeted: ''@JustinBieber @IAmWill got #ThatPower!! I am in L-O-V-E with the new song! (sic)''

will.i.am replied, saying: ''Thanks so much @BritneySpears. I can't wait 2work with u (sic).''

Scream and Shout' producer Lazy Jay - real name Jef Martens - has said how it felt ''surreal'' when he got a call from will.i.am asking to use one of his productions with the pop icon.

He said: ''One night I was just working in my home studio in Holland and I received a phone call and I wasn't sure who it was.

''When I picked up, it was will.i.am. I couldn't believe it. He said, 'Hi, it's will.i.am from the Black Eyed Peas, I've heard some of your stuff and I think it's really dope and I want to make record with you and Britney Spears. Is that okay'?' Of course, I said, yes. It was a surreal moment.''

will.i.am - who is also a member of the Black Eyed Peas - has also previously worked with Britney, on the track 'Big Fat Bass' from 2011's 'Femme Fatale' album.
