(CNN) — Kelly Osbourne landed in the hospital on Thursday after fainting on the set of E!'s "Fashion Police," a rep for the TV personality told CNN.
After the incident, Osbourne "was taken to a local hospital for further testing and is awake, alert and in stable condition," the rep said Thursday night.
The fashion correspondent tweeted Thursday, apparently from her hospital bed, as an attached photo indicates, saying she'd suffered a seizure.
"Thank U all 4 UR beautiful well wishes," Osbourne wrote. "[Y]es I did have a seizure they are just trying to figure out why?"
According to her rep, Osbourne was hospitalized "overnight for observation as a precautionary measure."
