Here is Chocolate featuring Ludacris. The quality is not that good but it's all I could find. Like explodingbird said, it wasn't officially released.
The rap goes something like this (from what I could understand)
Let me take you far beyond
in a whole other galaxy
travel in your mind
explore your sexuality
melt you imagination
and mould it into reality
your heart's my art gallery, girl
can feel the pictures that I paint?
cause all of them are related
like a mother to a son
but non of them overrated
aint no other, you the one
our destiny is to make it
gotta thank you just for saharing your world
something something something (disturbed by kylie saying "Like chocolate")
thinking that i'm incapable
of taking on the duty
of making you interchangable
the thought is sensational
it's perfect -----
ready to take the milky way
------
you know my --- got batteries in it
the bedroom
we lose calories in it
start families in it
don't worry cause the situation's under control
---- this
Ludacris down with Kylie Minogue.
