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.
Ross then quickly turned off the phone’s camera flash setting and returned it to the stunned audience member. She then resumed performing her classic dance hits.
The star performed in a an oversized, puffy red glittered gown.
Nine hundred guests paid $1,000-per-plate for the exclusive dinner. The money was used to support Make-A-Wish Southern Florida and attendees included some famous faces like director Brett Ratner and Scottie Pippen.
