Tulisa hints at 'surprise' Cowell X Factor appearance
Tulisa Contostavlos has hinted Simon Cowell may make a surprise appearance on 'The X Factor' later in the series.
The N-Dubz singer explained it is "quite possible" the 51-year-old music mogul - who quit as a panellist on the show after last year's show to concentrate on the launch of the US 'X Factor' - could return to the ITV1 talent competition for a "surprise" appearance.
