London, Jan 11 - British supermodel Naomi Campbell has turned down the chance to front a reality TV modelling competition after failing to agree on the terms of her contract.

The runway beauty was offered a role hosting the Britain version of America's 'Next Top Model', which is presented by model-turned-tv star Tyra Banks.

Campbell was in talks with TV heads over her pay and the amount of time she would be expected to be available for the project, but negotiations fell through at the last minute, reported imdb.com

'Naomi was really excited, but pulled out because she couldn't reach an agreement over logistics or the amount of time she would have to commit,' said a source.
