"After a five-day hospital stay, Kelly Osbourne has returned home and has been given a clean bill of health by her doctor," Osbourne's representative told E! News Tuesday.
"Doctors ran numerous tests and determined that this was most likely a onetime episode of which there are no conclusive results. She is looking forward to returning to 'Fashion Police' this week and getting back to business and life as usual."
Osbourne, 28, was hospitalized last Thursday after she suffered a seizure on the set of her reality TV show.
