Cowell: Leona is a great role model

Simon Cowell has dubbed his protegee Leona Lewis a "great role model" for the example she is setting for young people.

The music producer first discovered Lewis when she was a contestant on TV talent contest 'The X-Factor' in 2006, and has since shot to global stardom with her debut single 'Bleeding Love' - which has been number one in more than 20 countries.
