Britney Spears Premieres 'Till the World Ends -- Watch

Britney Spears premiered her video for "Till the World Ends" (directed by Ray Kay) on Vevo Wednesday morning.

Two versions were released: a director's cut and a choreography cut.

The videos can also be watched on Google TV, Boxee, and YouTube.

The futuristic clip features a leotard-clad Spears dancing around underneath Los Angeles. People are seen lifting up sewer covers to join Spears underground. In another scene, she wears a sheer red bodysuit.

She released her seventh studio album, Femme Fatale, earlier this week.

She recently performed on Good Morning America (the concert was taped in San Francisco), and on Jimmy Kimmel Live! to promote it.

She’ll also tour this summer.
