NicoleAn old Nicole Scherzinger song that's so far been hidden from the world has leaked all over the place.

'Part Of Me' — not an early version of the Katy Perry song, unfor­tu­nately — is a big old piano ballad, which Idolator spec­u­lates was meant for 'Killer Love', but who knows really.

It's not exactly 'Don't Hold Your Breath'.
