Oh no, Lovatics! Demi Lovato injured herself while on the Demi World Tour.

The 'Really Don't Care' singer appeared to have hurt her arm while at her San Antonio, Texas tour stop over the weekend, posting an Instagram picture of her arm in a sling.

"Welp. Looks like I won't be playing guitar, piano OR drums tonight," Demi captioned the snap, which she took right before her show that night. "San Antonio... Why did you have to go and make me fall so hard for you?!!"

While we don't know for sure how Demi hurt her arm, J-14 reports that Demi told fans that she slipped, fell and sprained her arm. Ouch!

Of course, the inspirational singer didn't let a little arm injury stop her from putting on an incredible show, later Instagramming this awesome vid from the concert:

Go, Demi -- and get well soon!
