E! "Fashion Police" co-host Kelly Osbourne remained hospitalized Monday following her seizure on the show's set Thursday.
"Kelly is still in the hospital under observation as a precautionary measure," her rep said in a statement. "She is in good spirits and looking forward to getting back to her busy schedule."
The exact cause of the seizure is still unknown.
