Diana Ross gives rare performance for charity fundraiser

Diana Ross surprised everyone when she appeared onstage to sing a few songs at a charity event over the weekend.
 
The night before the kickoff of the fest's 40th edition, the 71-year-old pop legend sang at the inaugural AMBI Gala.
 
Emceed by Canadian comedian Martin Short and closing with a rare, knockout 30-minute performance by pop legend Diana Ross, Wednesday night's AMBI Gala was the first of what its organizers say will be many fundraisers, in locales of relevance to the company, for causes they support. Subtitled "Cinema to Help the World," this one raised money — through sales of tickets to the event and a raffle that took place during it — for the Prince Albert II of Monaco Foundation, which champions environmental causes and aims to combat climate change.
