Were they sweating cooking oil?

Jennifer Lopez explained to Access Hollywood why she fell during her comeback performance at Sunday's American Music AwardsWhile attempting to do a move that involved climbing on a few of the dancers' backs, JLo explained the fall and said, "The guys backs were a little bit sweaty." To her credit, JLo got right back up and kept dancing. She hit the floor kind of hard, so I commend her for that. It really reminded me of this other famous fall:

Bey turned it into a flip, got up, and kept dancing. That's dedication for you! LOL!
