Demi Lovato isn’t afraid to be a diva…

The 20-year-old part-Mexican American singer and The X Factor judge performed live at last night’s VH1 Divas concert, getting the crowd on their feet with her show-stopping performance of her current single “Give Your Heart a Break.”

Held at Los Angeles’ Shrine Auditorium, this year’s all-star event featured performances by Pitbull, Kelly Clarkson, Ciara, Jordin Sparks, Melanie Fiona and Miley Cyrus. Adam Lambert served as the show’s host, while Havana Brown served as house DJ.

The event paid tribute to music legends Whitney Houston and Donna Summer with performances featuring current and classic dance hits.
