Kelly Osbourne was rushed to hospital after collapsing on the set of her E! show Fashion Police on Thursday.
It was initially reported by Entertainment Tonight that the 28-year-old suffered a seizure that lasted approximately 30 seconds, leading her to be taken to a Los Angeles hospital for treatment.
According to TMZ, Osbourne apparently turned to stand-in co-host Melissa Rivers, who was filling in for Giuliana Rancic, at the start of the taping and told her "I don't feel good", before falling out of her chair.
Her representative later released a statement saying that Osbourne had "fainted" during taping.
"Kelly Osbourne fainted on the set of E!'s Fashion Police today," her rep said.
"She was taken to a local hospital for further testing and is awake, alert and in stable condition. She will be staying overnight for observation as a precautionary measure. There are no further details at this time."
Osbourne later clarified with a post on her Twitter account that read: "Thank U all 4 UR beautiful well wishes yes I did have a seizure they are just trying to figure out why?"
