Beyonce Knowles hits us up with two music video premieres: "Single Ladies" and "If I Were a Boy". This girl knows how to work it! Beyonce is looking oh so fierce in her police uniform and then getting down in Single Ladies...

You got to love her! Both singles are from her upcoming album, due in stores November 18th.

Check out the videos below:
