Ginger Rogers did everything Fred Astaire did backwards and in high heels — but did she do it on a broken heel?

Shawn Johnson is making all the other Dancing With the Stars Season 15 All-Stars contestants nervous with what comes off as effortlessly strong dancing. Last week the judges raved that her Quickstep with Derek Hough was one of the best dances of all time, but they docked it points for rule breaking. This week Shawn and Derek tied for the top spot on the Week 3 leaderboard, just one half-point shy of a perfect score for their sexy Mambo.

Derek revealed that Shawn did the whole routine with a busted shoe. "We danced, we were happy — she has a broken heel and danced the whole dance on a broken heel,” Derek told E! News.

They showed how part of her heel was broken in half. Derek also shared a photo of Shawn’s shoes, writing, "Didn't realize but Shawn had broke her Heel before we danced ... This girl continues to amaze me . Proud Choreographer coach Friend.”

It takes more than a faulty high heel to faze an Olympian!
