Kelly Osbourne had quite the medical scare on Thursday after she was hospitalized following a seizure. And although nothing has been diagnosed, doctors are telling TMZ that Osbourne could be an epileptic.

Sources connected with the 28-year-old "Fashion Police" star tell TMZ that the seizure was far more serious than first suspected and doctors are still running tests. It's possible it was an isolated incident, but professionals are also saying that there's a chance Osbourne has epilepsy. Insiders also reveal that she'll be in the hospital for a few more days.

Meanwhile, Osbourne's mom Sharon Osbourne took to Twitter yesterday to reassure fans that her daughter was OK.

Kelly herself also shared an update on the social media site, thanking her followers for the support and confirming her medical situation.
