Kelly Osbourne confirmed that she did suffer a "seizure" yesterday on the set of E!'s Fashion Police. Like Justin Bieber, who also collapsed yesterday and tweeted a recovery photo along with confusion about what happened, Kelly tweeted...

Late Thursday night, Kelly's rep told People the 28-year-old star was going through "further testing and is awake, alert and in stable condition. She will be staying overnight for observation as a precautionary measure."

Best wishes to Miss Kelly!
