Teaser: Beyoncé - 'Run the World (Girls)'

Beyoncé starts a revolution in the third video teaser for “Run the World (Girls),” the first single from her fourth album. The Houston-bred superstar stands in front of a burning car, rides a black horse, and assembles her troops for battle in the post-apocalyptic clip. This means war.

UPDATE: Watch the extended trailer below, and look for the full premiere this Friday on VEVO.
