Whispers about Glee’s Brittany (or Heather Morris as the actress who plays her is called) working as a backing dancer for Beyonce in her pre-show choir days have been circulating for a while now. And in fact she was even invited to teach the Glee cast how to do the Single Ladies dance by the show’s choreographer before she landed the role of dippy cheerleader Brittany. Until now, we’ve never actually seen any footage of Heather performing with the mighty Beyonce, but thanks to some online rummaging we’ve now found a clip of Heather performing with the actual real Ms Knowles. We think she's pretty good, but what do you reckon?
