I still remember listening to the "greatest" leak back in 2010. It was one of my favourite tracks along with reloaded and out of control. I was so sad when they've decided to cancel this featuring. 

Anyways, this is my take on it. Hope you like it.

Beside the obvious use of the orginal vocals, I've also used some of the original stems,
The Drums were extracted from Britney's "Til The World Ends" and I've just added some elements over it.
I also used my own voice to add some extra vocals in the background

Keys, bass and synths were arranged by me.
