http://www.dailymail.co.uk/tvshowbiz/art...olice.htmlKelly Osbourne has confirmed she DID collapse on the set of Fashion Police on Thursday.

The reality star's publicist had early tried to play down the incident after dramatic images emerged of the 28-year-old being carried off set to an ambulance.

But straight-talking Kelly cleared up all doubt when she took to Twitter to explain to well-wishing fans what had happened.

She wrote: 'Thank U all 4 UR beautiful well wishes yes I did have a seizure they are just trying to figure out why?'

My whole world is collapsing.

First the Biebs , now this.
