Demi Lovato took a tumble onstage at the tail-end of her 20-minute set at the Z100 iHeartRadio Jingle Ball in New York City’s Madison Square Garden on Friday night.

“Guys, don’t you get it by now? Only cool kids fall on stage,” she tweeted later on in the evening, along with a happy face emoji wearing shades.

The 23-year-old, "Skyscraper", the singer had just closed out her set with her hit "Cool for the Summer" when she appeared to trip over her mic stand.

The concert was live-streamed for all to see, but the cameras happened to cut away right when the fall happened.

A live stream of the concert was posted on iHeartRadio's website.

Demi Lovato is flat on her back -- arms and legs flailing about, one of her crew members runs onto the stage to pick up the mic stand.
The award-winning singer had just finished a flawless performance and thanked the crowd: 'New York, I'll see you soon! I love you!'

Back in July, Lovato performed at a pool party in Los Angeles to promote -- you guessed it -- “Cool for the Summer” and fell chest first on the slippery platform.

Demi joined an all-star line-up on Friday for the festive bash, with singer Selena Gomez, musician DJ Zedd, rapper Fetty Wap and girl group Fifth Harmony all hitting the stage.

On July 2015, Demi released her lead single from "Confident" title "Cool for the Summer."

She performed on October 2015 a "Cool for the Summer" and "Confident" medley, and "Stone Cold" on Saturday Night Live during the series forty-first season.

On October 26, 2015, Lovato and singer-songwriter Nick Jonas announced that they would tour together on the "Future Now Tour."

Currently, Celebrity Net Worth lists Demi Lovato's net worth at $20 million, making $2 million a year.
