So. We've all heard of the walk-off, right? This is when two people, who believe they have Naomi Campbell- or Gisele-like catwalk struts, go head-to-head against each other to see who, in fact, is the real diva with the equally mean walk. Well, this is not a walk-off.

No, this is what Style.com is calling a "dance-off" and it's just as epic as that other thing. In this clip, YSL Beauty campaign babe Damaris Lewis goes up against famed choreographer Joshua Pelatzky. They do a little hip-hop dancing, tapping, and a lot of other dance moves that we can't quite comprehend. Watch and enjoy!
