Serena Williams makes a cameo in Beyonce's new music video

Serena is that you? The 21-time Grand Slam singles champion can now add music video-star to her repertoire.

The reigning queen of tennis set the social media world abuzz when she appeared dancing alongside Beyonce in her new "Lemonade" music video and quickly confirmed the rumblings:

Beyonce's visual-album debut on HBO made a splash for multiple reasons. The caliber of the music, paired with what the lyrics seemed to suggest -- that she and husband Jay Z were at odds -- were enough to make the Beehive squirm.

Add in a cameo from the World No. 1, and this is suddenly as noteworthy as when Destiny's Child reunited at the Super Bowl.

Williams also posted a picture to her Instagram account commemorating the moment and giving us a serious case of deja vu from her 2015 Sports Illustrated "Sportsperson of the Year" cover:

Who run the world? Serena and Queen B. We will gladly bow down now.
