Tulisa: Duo will bring 'fun' back to 'X Factor'

Tulisa Contostavlos insists 2 Shoes will bring "the fun factor" back to 'The X Factor'.

The N-Dubz singer – who mentors the Essex-based duo, made up of Lucy Texeira and Charley Bird – insists if the pair are voted back into the ITV1 show tomorrow as a replacement for axed Frankie Cocozza, they will fill the void left by former contestant Johnny Robinson.
