Britney Spears' 'Till The World Ends' Gets R. Kelly Treatment

Following all-girl remix featuring Nicki Minaj and Ke$ha, R&B singer proffers his own mix of the song.

Did R. Kelly place his vote for his pick for Song of the Summer by jumping on a new remix of Britney Spears' monster smash "Till the World Ends"? Following the all-girl remix featuring Nicki Minaj and the song's writer, Ke$ha, this new version of the Femme Fatale single gets some love in the club from Kells.

On the new mix, after Brit sings the first verse and the chorus, Kelly comes in singing, "Slide up in this club/ This beat's got me in love/ Till I just don't care/ It's like I'm walking on air/ It's a party right here." He then goes on about partying till the world ends, his Auto-Tuned vocals dancing over the track until the song's breakdown, where he mixes his vocals with Spears'.

Toward the song's end, Kelly does some vocal runs over the song's chorus as it plays out, keeping with the integrity of the Dr. Luke-produced track.

Remixes certainly aren't new for Kels, who's reworked several of his own tracks, including "Ignition" and "Bump N' Grind," spinning new life into the songs that had already become fan favorites. He's also remixed tracks for an eclectic galaxy of stars like Whitney Houston, Usher and soul legends the Isley Brothers, to name a few.

As for Spears, several of her Femme Fatale songs have been remixed in various ways including the Bollywood "Till the World Ends and the house version of "Hold It Against Me." A Neptunes remix of "Boys" dubbed the "The Co-Ed Remix" climbed to the top of "TRL" back in 2002, and she released a remix album in 2005 called B In The Mix: The Remixes, with club-ready up versions of "Me Against the Music," "Everytime," "Toxic" and more.

"Till the World Ends" isn't the only Song of the Summer contender that's getting reworked by a male pop star. Over the weekend, much to the delight of Mother Monster herself, Nick Jonas put his own signature acoustic singer/songwriter stamp on her summer contender "The Edge of Glory."

Lady Gaga tweeted, "Swoon! Nick Jonas singing 'The Edge of Glory.' On my way to press conference in Taichung, listening to it. So dreamy! X."

Using only his acoustic guitar, Jonas played his version of the triumphant pop track to a audience of fans who seemed charmed by his rendition of the Born This Way single. "@ladygaga the pleasure is all mine," he later tweeted. "That is a beautiful song. Keep inspiring the world."
