Celine Dion, 47, stunned in a low-cut gown as she sang a duet with Andrea Bocelli, 56, in Las Vegas on Saturday, Daily Mail reported.
The 47-year-old made the appearance for Keep Memory Alive's 19th annual Power Of Love Gala at the MGM Grand Garden Arena.
Benefits such as this, which fund disease research, hit close to home for the singer. Her husband René Angélil, 73, has been battling throat cancer since 1999.
The My Heart Will Go On singer wore a floor-length black gown as she took the stage.
The dress flowed to her ankles and plunged around her cleavage, showing off her very slender frame.
The Canadian wonder looked stunning with her auburn hair dangling in wavy curls.
