At 70, Diana Ross is still a disco diva.
The “I’m Coming Out” hitmaker shocked a socialite on Saturday night at the InterContinental Miami MAKE-A-WISH Ball when she stopped mid-performance and snatched the attendee’s phone because it was distracting her.
“[She said] ‘Darling, I can't see with that flash,’” an insider at the ball recounted to FOX411.
