Do you like being upright? What is your problem, even? The ground is good enough for Demi Lovato; the ground should be good enough for you.

Demi Lovato, person who falls, fell after a set at iHeartRadio's Jingle Ball on Friday (December 11). Demi Lovato was oh-so-erect through her 20-minute set, but HERE'S THE THING: Once she waved goodbye to the crowd, equilibrium set in and was like: have a nice trip, see ya next falllllll.

And then Demi Lovato fell. Again.

But guess what! After wiping out, Demi Lovato did not make a big stink of things, no sir. Demi Lovato played it cool, oh so cool, cool as a cat. She flailed her arms and legs as if it had all been part of a dance, an experience, an experiment.

"Guys don't you get it by now? Only cool kids fall on stage," tweeted Demi Lovato, fallen, cool.

Demi Lovato injured her leg after falling in 2013, but she wasn't onstage. She was on her apartment's floors, as evidenced by the tweet "Never, ever, ever, EVER let your roommate clean your hardwood floors with Pledge..." Demi Lovato also fell in 2014, a fall that left her outfitted in a sling. And of course, she ate it during a poolside performance of "Cool For the Summer"  back in July of this year.

Check out the clip, and if you're privy to sneakers with especially good traction, consider cluing Demi in.
