E! presenter Kelly Osbourne has confirmed that she suffered a seizure on the set of the Fashion Police yesterday.

The Daily Mail reports that her publicist had earlier tried to play down reports of an incident after dramatic images appeared showing the 28-year-old being put into an ambulance.

The former reality star took to Twitter to clear up the confusion saying "Thank U all 4 UR beautiful well wishes yes I did have a seizure they are just trying to figure out why?"

Osbourne was taken from the set to a hospital in Los Angeles where she stayed overnight. She had been filming the latest episode of the Fashion Police which is hosted by Joan Rivers. Kelly sits on the panel alongside Giuliana Rancic, who was missing for yesterday's filming, and George Kotsiopoulos.
