Cheryl Cole lost weight with the Dukan diet and a stint in boot camp

Cheryl Cole has reportedly lost weight with the Dukan diet and a stint in boot camp.

The Girls Aloud singer allegedly put on weight during her stint on the US X Factor where she apparently was homesick and spent her evenings in her LA hotel watching movies and taking comfort in Hobnobs biscuits and junk food.

However, since returning home following her departure from the talent show she has been working hard to get her body back in shape.

It is rumoured that she has been following the Dukan diet plan and she also spent seven days at a luxury UK fitness retreat two weeks ago.

Cheryl spent four to six hours a day exercising during her time at the boot camp.

She also had treatments, including thalassotherapy pool sessions and detoxifying seaweed wraps, which promise to melt inches from your body.

A source told Now magazine: "Cheryl Cole's been exercising like a demon because she's determined to look her best for Ashley Cole.

"He always tells her he likes her looking `fit' and that was motivation enough."
