Do NOT underestimate Ke$ha's cartwheel.

Ke$ha's not just a singer, y'all -- the girl can cartwheel! And let's not take that lightly, OK? Because even after all those years of the "gymnastics unit" in P.E., my cartwheel still turns into a sloppy, poorly executed round-off. But not Ke$ha -- I mean, do you see that form? "Arms straight, legs extended!" as my gym teacher would say. And did we mention this all went down while the "Supernatural" singer rocked a bejeweled leotard and fishnet stockings with a giant hole in them? #Chutzpah.

Check out more photos of Ke$ha at KIIS FM's 2012 Jingle Ball after the jump.

Along with other singers like Justin Bieber and Alicia Keys, Ke$ha hit the stage at KIIS FM's 2012 Jingle Ball, and as you can see, the "Die Young" singer gave the audience a show and a half. Not only did she nail her cartwheel routine, but there was some sort of stunt with a portable cymbal and a truly on-point Rockette-style high kick. Say whatever you want about K-dawg, but there's no denying that girl can BRANG it on stage. Also, props on that sparkly gold mic you've got going on there, honey.
