The Beyoncé revolution begins now. The global superstar strikes a bold pose in the sand on the cover of “Run the World (Girls),” the first single from her highly-anticipated fourth album. The photo was taken from the singer’s recent video shoot, where she wore the same yellow dress and black stiletto boots.

After lots of speculation, an official press release went out this afternoon. The song will premiere on radio tomorrow at 8 a.m. EST in the U.S. and will be available for download on iTunes worldwide starting Thursday morning.

“Run the World (Girls),” which samples Major Lazer’s “Pon de Floor,” was produced by Switch with additional production by Beyoncé and Shea Taylor. The song was written by Terius “The-Dream” Nash and Beyoncé.
