New Delhi, Feb 14 (ANI): Simon Cowell has claimed that his X Factor show is the "least racist show in the world". The 54-year-old music mogul slammed Chris O'Dowd's claim that the viewers of his show are "racist" as they vote black singers off the contest early each year. Cowell sites the example of Alexandra Burke and Leona Lewis, and made digs at the Irish comic saying that it's not only "ignorant" but actually "insulting" to hear him say that to the audience.
