This time the duo made in music perfection heaven teamed up on Will's new single "#ThatPower."
The new single is the second song the two singers have worked on.
Will.i.am introduced the song by tweeting about it on Twitter this morning.
"This is it...its live and officially launched to the world...
Justin and Will actually recorded the song while in London recently, during the BRITs. The tune is a really fun dance song and a bit different from their last song together. We like!
"#ThatPower" will be the fourth song released Will.i.am's album #willpower.
