Britney Spears sure knows how to work fast: Only a few weeks after the release of the music video for her number-one single, 'Hold It Against Me,' the Grammy-winning superstar is already putting on another show -- this time, in the video for her follow-up single, 'Till the World Ends.'

Spears has never looked better in this almost-too-hot-for-the-Internet video, in which the leather-clad singer performs and dances in some type of underground nightclub.

Even better: The video is being released at the perfect time for Spears, whose brand-new CD, 'Femme Fatale,' just debuted at number one on the Billboard 200 albums chart, with 276,000 copies.

Watch the video now, then sound off: Is this her best video yet?
