Kelly Osbourne has been hospitalised after suddenly collapsing into a seizure on the set of her fashion diss show 'Fashion Police'.

The TV star was filming at the E! building on Wilshire Blvd in LA alongside her co-star Melissa Rivers before she suddenly stopped and told her, 'I don't feel good.' She then keeled over and started having violent convulsions before seemingly a member of the audience came up to administer first aid. It wasn't long before the star seemed to come round from the ordeal but she was still subsequently taken to an ambulance on a stretcher with a white sheet covering her body so as not to give away who she was. One person held up another sheet in an attempt to screen the commotion from view. According to TMZ who obtained pictures on the ambulance's arrival, Kelly has never before suffered any kind of seizure. Her co-star Joan Rivers told the publication that after seeing her, she seemed 'fine' and Kelly herself has Tweeted her fans to reassure them of her condition.

'Thank U all 4 UR beautiful well wishes yes I did have a seizure they are just trying to figure out why?' She wrote on her Twitter page accompanied by a photo of her heavily tattooed forearm being hooked up to a drip. Us Weekly have reported that they've been told she is 'awake, alert and in stable condition' but no other information has yet been uncovered.
