Kelly Clarkson has been ordered by advertising executives to slim down if she wants to front a new healthy drinks campaign. Clarkson has signed a contract to promote her favorite flavor of Vitamin Water but bosses at Glaceau, the company that manufactures the drink, feel she needs to lose some weight before they use her to advertise the beverage.

Kelly - who will promote Kiwi and Strawberry flavoured 'Focus' Vitamin Water - has been put on a strict all-organic diet and has even hired a professional chef to prepare all her meals while on her Addicted tour.

The singer previously revealed she joined forced with Glaceau to help encourage young people to make healthier choices. She said: "Why I love the Vitamin Water campaign is a lot of kids just down soda and it's not good.

"Obviously I have a lot of young fans, so that's why we teamed up. I just realised that I have a platform. If you have a voice, you might as well make it a positive one."
