The British-born, New York-based Lillywhite has mounted a full-scale campaign to be considered for the job Cowell will be vacating after this season of the hit show to helm the US rollout of his British TV series "The X Factor." Lillywhite has hired an agent and publicist.

He also has posted a short clip on YouTube extolling his bona fides, and he recently filmed "a slightly more professional" video that will be out soon.
