Kelly Osbourne was taken to a hospital in Los Angeles, after she suffered a seizure while filming her E! show, Fashion Police.
The seizure, which caused the 28-year-old singer/fashion designer to fall to the floor, lasted for approximately 30 seconds, ABC News reported.
Melissa Rivers and crew members, as well as an EMT who happened to be in the audience, rushed to Osbourne's side to help when she fell.
Osbourne was shielded by blankets on her way out of the studio to be taken by ambulance to the hospital.
Joan Rivers was also on set at the time, and the seizure occurred at the end of a one-hour taping of the show.
This isn't the first health issue for the Osbourne family. Her brother Jack was diagnosed with multiple sclerosis last year, while her mother, Sharon, successfully battled colon cancer about 10 years ago, and underwent a double mastectomy when it was determined that she carried the gene for breast cancer.
