Demi Lovato's got a mean right hook!
That's what Rocky star Sylvester Stallone found out after a bout with the “Confident” singer, who knocked him to the ground!
"Just knocking out Rocky (@officialslystallone) easy day at @unbreakableperformance," the 24-year-old artist posted to Instagram on Wednesday.
In a video from the Unbreakable Performance Center in Los Angeles, Stallone can be heard joking, "I slipped! I swear, it was an accident!" Moments later, the duo sweetly hugged it out.
The 70-year-old actor shared the same clip to his own Instagram, writing, "Rocky gets knocked out by his long-lost daughter, Roxana … Starring Demi Lovato @ddlovato. The Unthinkable At Unbreakable."
Lovato -- who frequently shares video of her workouts on social media -- is no stranger to the boxing gloves.
Last month, ET spoke to personal development coach Mike Bayer -- who founded and now co-owns the mental health facility CAST Centers with Lovato -- about how staying physical helps the singer achieve her own wellness goals.
“Trying to make yourself do something that you don’t enjoy doing just doesn’t work, so my job is to figure out a strategy," he explained. "Demi is doing Jiu-Jitsu, and she’s already got a stripe on her belt. She loves Jiu-Jitsu, and she loves kickboxing, and I create a plan around that because I knew that for her, that would be a passion. That would be enjoyable. That would make her feel accomplished."
Doing what she loves has clearly payed off for Lovato -- we wouldn't want to face off with her in a ring anytime soon!
