While filming a live show of Fashion Police, Kelly Osbourne fell out of her chair and began to have a seizure. Prior to her fall she turned to her co-host and explained she wasn’t feeling well. 

After the episode, she was sent to the hospital. Joan Rivers tells TMZ that she saw her and she’s doing okay after the incident. There isn’t any news on her current state or what caused the seizure.

Kelly later tweeted from her hospital bed.
