Kelly Osbourne has been banned from driving following her seizure earlier this year (13).
Ozzy and Sharon Osbourne's daughter suffered a health scare while filming U.S. Tv series Fashion Police in March (13) and spent several days in a Los Angeles hospital while doctors attempted to discover what caused her seizure.
Osbourne has now revealed she is taking precautionary medication, and has been told she cannot sit behind the wheel of a car in case she suffers a relapse.
She tells Britain's Hello! magazine, "I don't know if I'm epileptic or not - it's a waiting game right now. It's scary and confusing. I'm hoping it was just a stress-induced seizure, but I have to be on anti-seizure medication for a year and I can't drive in case I have another episode.
"Not knowing what caused it is the worst thing. There's a chance it won't happen again and I hope it doesn't, though I don't remember it."
