Kelly Osbourne -- and her family, no doubt -- is keeping a healthy sense of humor in the days following her scary seizure on the set of Fashion Police March 7. "My life now is like an episode of House," Osbourne, 28, tweeted on Sunday. "The impending fight against death and the look of fear in everyones faces!"
Indeed, there's definitely a bit of uncertainty in the Osbourne household as doctors continue to discover what led to her episode. "There is absolutely no confirmed diagnosis regarding Kelly's condition," a rep for the TV host told Us Weekly on Saturday. "She is under a doctor's care and they are continuing to run tests. Kelly is fine and thanks everyone for their continued support."
A source close to the family added 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."
"More than anything it was just scary," Fashion Police costar Melissa Rivers, who helped her costar out as paramedics arrived, told ET Online of the situation. "I just laid on the ground holding on to her until the paramedics came."
