I thought her album is already done?

It's not for her album.

She posted the pic on her instragram aswell, with the message it is for his album, not hers

Good sis Nicole doing demos for J.Lo

flawlessssssss

you are just not ready for that Scherzinger and Afrojack SMASH

Maybe she's session singing a few tracks for him?

YASS

sis

I didn't know that J.Lo is still taking Nicole's leftovers like she did with RedOne tracks Nicole rejected.

Er... Nicole Scherzinger is a session singer for RedOne, will.i.am, David Guetta, Dave Aude, Phantom Boyz, etc. so she's probably doing the same for Afrojack. So it could bloody well be a J.Lo track, you know.

I love both my queens but this **** made me.

I hope it's somewhere along the lines of "Take Over Control."

for all I know she has yet to work with David Guetta. (since Club Can't Handle still isn't confirmed)
I am pretty sure this is just not session singing, that could be partly the case, but I doubt it was the only reason she worked with him!

Huh? Nicole has never worked with Guetta and the rest are producers she's actually worked with. "Beautiful People" by the Phantom Boyz was supposed to be a solo single for Nicole, but it was rejected and then given to Christina Aguilera. The only exception in the that list is probably will.i.am and that's because they're friends so she's going to do favors for him.
