Demi Lovato is known for having a pretty big voice and is a pretty big role model for young people.
Recently the 25-year-old singer was performing one of her new songs from her chart-rising record Tell Me You Love Me
when she was not feeling well.
She started to sing a few notes which sounded normal! She then went to bring out a high note, for which her voice cracked.
It was totally cool though, Lovato just dropped an f-bomb, she and the fans had a laugh and she got right back into it!
"Even when I lose my voice on stage my fans know how to keep me from being down.. thank you my Lovatics I love you," she later tweeted.
