Britney Spears feat. R. Kelly: "Till the World Ends [Remix]"

Kelly slithers in with no shame: Does he actually sing, "It's a party right here hosted by Mr. Sex Addiction"?! Not as fab as the Ke$ha/Nicki Minaj remix (best use of chicken clucks this year!), but not as scene-stealing, either. He's a gentleman.
