Justin Bieber isn't the only celeb who had a health scare yesterday; on the set of the E! network's "Fashion Police," Kelly Osbourne had a seizure and was rushed to the hospital.
Osbourne appears to be doing better, even tweeting a picture from her hospital bed and noting that confirming that she did, indeed, have a seizure.
"Yes I did have a seizure," Osbourne tweeted, "they are just trying to figure out why?"
Osbourne was apparently sitting in a chair in front of a full audience, TMZ reports, when she told Giuliana Rancic "I don't feel well," and then fell from her chair and began shaking. Fortunately, there was a first responder in the audience who helped her until the ambulance could arrive.
Joan Rivers, who was also there when Osbourne collapsed, told TMZ that she's "fine."
Osbourne's mother, Sharon, declined to comment.
