The mother-of-four who reduced Tulisa Contostavlos to tears on The X Factor has been revealed as an underwear model. Michelle Barrett, who reminded judge Contostavlos of her mother when she performed 'All the Man I Need' by Whitney Houston, has revealed that she took part in Ultimo's 'Real Woman' campaign earlier this year and posed for billboards in just a bra and knickers. Barrett told the Daily Mail: "Posing in just your pants is very full-on. But on the day the shoot was very prof­essional and the photo­graphers put me at ease really ­quickly." She said that she was nervous about the photos and had second thoughts at the last minute but was thrilled with the final result. > 'X Factor' Cher Lloyd: 'Tulisa could teach me a few things'
