Before you start lecturing Simon Cowell, you may want to turn your attention to Sinitta, Simon's ex and 80's popstar, who believes she has more experience. Talking to Star magazine, the singer and full time Simon Cowell Leach revealed that she's got the edge over Mariah.

She said: "As a vocal mentor I’d say she is better than I am vocally. But she won’t be better at mentoring the talent than I was.”We're pretty sure Mariah could get the better over Sinitta any day and with Mimi as a judge, at least we won't have to watch Sinitta fawning over Simon every minute of the day!
