LOS ANGELES, Calif. – Kelly Osbourne is resting at home after being hospitalized for five days following a seizure.

A spokesman for the 28-year-old TV personality says doctors have given Osbourne “a clean bill of health,” finding no conclusive results explaining why she collapsed on the set of E!’s “Fashion Police” last week.

Publicist Marcel Pariseau tells E! News that Osbourne “is looking forward to returning to ‘Fashion Police’ this week and getting back to business and life as usual.”

Osbourne took to Twitter on Monday to thank the doctors and medical staff at Cedars-Sinai Medical Center for “fixing me up enough to go home.”

In another tweet, she compared her life to an episode of the medical show “House.”
