Britney Spears is wasting no time in releasing new songs off her upcoming album Femme Fatale, and now the hot mama of two is already working on her next video for "Till The World Ends."

The 29-year-old singer released this photo on her Twitter page to rev up excitement for the new video ... and it's working! While sitting on a director's chair in an LA studio, Britney rocked some ripped tights and a studded leather jacket. We kinda like this raunchy side of our girl.

In addition to the sexy photo, Brit tweeted:

    "Day 1 of the Till The World Ends videoshoot. Just wrapped my first big dance number. Taking a well deserved break people."

As for the single, it was co-written by Dr. Luke, Max Martin and Ke$ha. Can't wait to see the finished product!
