R.Kelly has joined Ke$ha and Nicki Minaj by remixing Britney Spears' single 'Till The World Ends.'

The R&B crooner's version still includes Britney's vocals as well as his own verse in which he sings about the kind of women he wants to party with. R Kelly's vocals surprisingly blend well on the party track, although we can't imagine him performing it live.

It is not known whether his version is the official remix to the track.
