Demi Lovato was left red-faced after an incident at her Kansas City concert this weekend.
The 19-year-old singer was strutting her stuff when she accidentally pulled out one of her hair extensions during a particularly energetic dance move.
But ever the professional, Demi didn't let it get in the way of her performance and she soon regained composure and simply carried on with the number.
But she's not the only young US star to have suffered an on-stage mishap - Taylor Swift, 21, flashed her knickers to the audience after a gust of wind lifted her dress.
