ABC/Paula LoboDemi Lovato packs quite a punch.

The singer revealed on Instagram Tuesday that she accidentally knocked her trainer’s tooth out during a boxing match.

In a video clip, her good-natured coach Jay Glazer exclaims, “Ring the bell! Demi knocked my tooth out!” We see him sporting a gap in his smile, holding the missing chomper.

“I’m sorry!” Demi says, laughing, with her boxing gloves still on. “She’s not sorry!” Glazer jokes.

“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!!!” Demi captioned the video.

She added, “So coach, when’s my first fight?!”

Demi looks happy and healthy in the clip. Earlier this week, a source told Entertainment Tonight that she is committed to her sobriety eight months after her near-fatal overdose.
