Mariah Carey shows off her new slimline shape on the cover of her latest single Touch My Body.

Obviously, she has lost a lot of fat and a little muscle. She does yoga and strength training – her thighs have become really hard. Now she has the body she had in high school. Her jean size is the same as when she was 17.

She is pleased that she’s inspired the likes of X Factor winner Leona Lewis, 23.

‘It makes me feel old when girls like Leona say I’m their role model,’ she admits, ‘although I do have the body of a 12-year-old!’
