Demi Lovato isn't one to fuss over her hair.

The pop singer accidentally pulled out one of her hair extensions while performing in Kansas City, Missouri. But rather than acknowledge it, Lovato kept on singing and dancing -- with that hair extension in hand -- proving that she is a professional.

The singer, who played the title character in the Disney series Sonny With a Chance, has had a strong comeback this year after undergoing treatment for health issues in 2010.

Her single Skyscraper was released to critical acclaim and her album Unbroken has made waves.

The 19-year-old songbird seems to be taking care of herself while on tour.

New Orleans you were amazing... Now it's time for some much needed rest, she tweeted on Nov. 27.
