The 28-year-old suffered a seizure on the set of her TV show 'Fashion Police' last Thursday, said the Hollywood Reporter.
"She has been given a clean bill of health by her doctor. Doctors ran numerous tests and determined that this was most likely a onetime episode of which there are no conclusive results," the representative said.
"She is looking forward to returning to Fashion Police this week and getting back to business and life as usual," the representative added.
Sharon Osbourne, Kelly's mother, said that she was thankful that her daughter's seizure had been captured on tape so that doctors could better identify her condition.
"She's on medications. Nobody knows why she had it, can't figure out a reason why. But she is fine, and naughty," she added.
