Spice Girl Mel B, who recently gave birth to her third child, has been confirmed as the new face of weight loss brand Jenny Craig. 

The singer, presenter and full time mother revealed that a particularly blunt newspaper headline pushed her to do something about the weight she had gained during her pregnancy and the Jenny Craig program seemed perfect:

"I've my humps and bumps, but when a newspaper described my shape as the 'bootylicious, curvylicious, post-baby body of Melanie', I knew I had to do something. I had to get the eating under control."

She has been tweeting to her followers about her experiences with the company so far and reassured her fans that she has no intention of losing her curves:

"Hey peeps I love love love my curves, I don't wanna lose them I just want them smaller, and #jenny is gonna help me do that!"

A spokesperson for the weight loss organisation, Amy Smith, explained that "Jenny Craig's team of nutritionists and doctors have created a program especially for women like Mel who have recently given birth, that takes into consideration the nutrient levels needed for breastfeeding women."
