Kelly Osbourne's illness is still a mystery after she had a seizure Thursday. Osbourne first told the public about her seizure the next day when she tweeted a picture of her arm attached to an IV.
Most recently, the E! "Fashion Police" co-host tweeted, "My life is now like an episode of House = the impending fight against death and the look of fear in everyones faces!"
A source close to the family told Us Weekly that Osbourne was "really scared by the seizure and that doctors are running every possible test . . . Could be epilepsy but also could be an allergic reaction or something else."
The latest statement from Osbourne's PR people: "There is absolutely no confirmed diagnosis regarding Kelly's condition at this time. She is under a doctor's care and they are continuing to run tests. Kelly is fine and thanks everyone for their continued support."
Osbourne, 28, was at work when she collapsed and was hospitalized. She has been working on the set of E! Network's "Fashion Police" where she discusses and comments on celebrity fashion. Osbourne is the daughter of British rocker Ozzy Osbourne and "The Talk" co-host Sharon Osbourne. She has also appeared on "Dancing With the Stars."
