The 18th annual “A Night at Sardis” musical revue and gala drew a slew of A-list celebs including Anne Hathaway, Fraiser star David Hyde Pierce and Will & Grace’s Eric McCormack who all belted out Broadway tunes to raise money to benefit the Alzheimer's Association.

The event was held Thursday night at the Beverly Hilton in Los Angeles where the always stunning Demi Moore - who was presenting an award at the event -- walked down the red carpet arm-in-arm with her hunky husband Ashton Kutcher. Brother's and Sisters star, Gilles Marini shouted in excitement, "I've never seen Demi Moore before, Ashton you’re so going down."

On a night where celebrities were giving back, RadarOnline.com’s reporter Viviana Vigil asked what was the most selfless act they've had done for them.
