Reality Tv star Kelly Osbourne has been hospitalised after suffering a seizure on the set of her E! Tv show Fashion Police in Los Angeles, according to U.S. reports.

It is suggested that Osbourne fell to the ground and began shaking after complaining of feeling ill. An ambulance was called for the 28 year old, who has previously battled substance abuse issues, and she was taken to a local medical centre for treatment.

A representative for the star had not responded to a request for comment as Wenn went to press.

Osbourne shot to fame as the star of reality Tv show The Osbournes, which documented her early drug issues.

She entered rehab three times between 2004 and 2009 to battle an addiction to painkillers. She has since become a Tv star in America, appearing on Dancing With the Stars and Fashion Police. She is also a regular contributor to E!'s red carpet awards show specials and recently interviewed celebrities at the Oscars.
