Demi Lovato PUNCHED her trainer!

Demi Lovato tried to keep a low profile ever since she was out of rehab, focusing on other activities. Like, for example, jiujitsu and boxing.

And she seems to be enjoying herself, but went through a little incident: she knocked one of her trainer’s teeth out!

The whole moment was shared by Demi Lovato on her Instagram, admitting that he did it while her training was wearing a mouth piece!

Check it out:

Pretty rough, right?

Demi can be heard saying “I’m sorry,” while pumping her fists in the air. Hopefully, her trainer was ok after this and got his tooth fixed because…well, she kicked him pretty hard and that must have hurt.

Guys, this is a chick you really don’t want to mess with!
