Diana Ross gave one of the most emotional performances of her career on Tuesday night.

The legendary singer revealed to the audience at her Gibson Amphitheater show in Los Angeles that her father had passed away earlier that morning, PerezHilton.com has learned.

Like Kanye, the singer decided to go on with the show.

“It was very touching,” one concertgoer tells us. “Diana was close to tears throughout the show and at one point brought out her entire family on stage in celebration of her dad.”

Ross told the concertgoers that she was flying to Detroit immediately following the show for the funeral.

Our condolences.
