Osbourne reportedly told guest host Melissa Rivers, who was filling in for Giuliana Rancic, “I don’t feel good” before falling out of her chair. Ozzy’s daughter then began shaking and an ambulance rushed to the scene.

Osbourne was taken to the ambulance on a stretcher, covered by sheets to shield her from the media, TMZ reported.

"She's fine," Rivers said in a video posted Thursday afternoon on TMZ. "We just saw her."

Spokeswomen for Sharon Osbourne and Melissa Rivers, Joan's daughter and executive producer of "Fashion Police," declined to comment.
