Heather Morris, aka Brittany S. Pierce, has quickly become our favorite Gleek thanks to her awesome one-liners and killer dance moves. So when I saw that Esquire had posted a video called “How To Dance With Heather Morris,” I got kind of excited. I was picturing “Darrin’s Dance Groove” from back in the ’90s, thinking I’d get some of Heather’s patented “Single Ladies” dance steps broken down move-by-move. Instead, I got the above video of Heather shaking her groove thang in a skimpy leotard and teased-to-there hair. Hot, sure? But helpful, not so much. I think I’ll skip the humping the floor move for now.
