Demi Lovato gave her usual flawless performance on Dancing With The Stars. She sang her hit single "Skyscraper", and her vocal performance was accompanied by four back-up dancers who did a "beautiful contemporary routine to" Demi's "inspirational ballad." It was a great night for Demi and her huge loyal fan base, and it represented another triumph for her in her efforts to rebuild her career and her life after her stint in rehab last year. One aspect of Lovato's Dancing With The Stars appearance was quite unusual however. In fact, it was downright shocking. The former Sonny With A Chance star sported a pierced nose.
