Now that's an LBD!

Demi Lovato showed off her curvaceous figure in a form-fitting black dress at the Perez Hilton One Night pre-VMAs party on Saturday night.

With her hair styled in glamorous waves and sporting classic red lips, the 18-year-old singer showed no signs of the "emotional and physical" issues including a "life-long" eating disorder and other problems that caused her to enter a rehab facility last November.

She continued her triumphant comeback the following evening at the MTV Video Music Awards, hitting the black carpet in a sexy plunging silver Mandalay dress and posing for pics backstage with ex-boyfriend Joe Jonas
