Sorry not sorry! Fans of Demi Lovato obviously know the singer is no stranger to boxing, and she literally just knocked a guy’s tooth out during her latest session in the gym. Yep, you heard that correctly.

Fans were completely shook (in the best way, of course) when the 26-year-old Disney Channel alum posted a video to Instagram, showing her coach’s tooth being knocked out from Demi’s mixed martial arts skills. The victim? Sports host and trainer Jay Glazer. But don’t worry, you guys. He wasn’t bothered in the slightest. In fact, he was proud of the Camp Rock legend for her powerful punch!

“Ring the bell! Demi knocked my tooth out,” he said in the video, smiling ear to ear. See for yourself!

Demi captioned the post, “Holy s–t I literally knocked @jayglazer’s tooth out during training this morning – while he was wearing a mouth piece!!!! Hahahahaha sorry (not sorry) Jay!!! So coach, when’s my first fight?! #unbreakableperformance.”

The “Cool for the Summer” songstress is a boxing gym regular, and she even opened up about her love of jiu-jitsu in a 2017 interview.

“I first got into jiu-jitsu because I loved watching people grapple,” she told Self. “I think it’s really cool to learn something that helps you with self-defense.”

She went on to explain why MMA came to be one of her favorite forms of exercise.

“Sometimes I get really bored when I do just an hour of cardio, so sometimes I struggle with boredom. But that’s why I like to train MMA, because it keeps it exciting,” she added. “I used to work out too much, and then I stopped working out because I got burnt out on it. A few years ago I picked it up again with a trainer. I liked cycling, then I went from cycling to just strength training mixed with cardio, and then I found MMA.”

If one thing is for sure, it’s that she’s really good at it — and her coach’s missing tooth is proof!
