Britney Spears bulimia fear

Britney Spears is reportedly abusing laxatives and vomiting after meals.

The 'Womanizer' singer, who recently unveiled a newly toned figure which she claims is down to a healthy eating and fitness regime, is battling an eating disorder, one of her bodyguards has allegedly revealed.

A source close to one of Britney's bodyguards told America's Star magazine: "Britney's diet consists mostly of Taco Bell and turkey jerky washed down with Red Bull.

"She throws up after meals, both at home and at restaurants and she isn't very discreet about it. People around her think she's bulimic."

It has also been claimed the 26-year-old star is taking diet pills in order to maintain her new slim shape.

Another insider revealed: "The pills are like diuretics. She has to go to the bathroom constantly. It just runs right through her. And everyone knows she still throws up when she's eaten too much. You can smell it in the bathroom."

It was previously reported Britney is suffering from bulimorexia, an eating disorder which sees her both starving herself and then bingeing and making herself sick. The singer - who is said to have lost around 28lbs in the last year - reportedly starting shedding weight when she began training for her upcoming world tour.

A source said: "Britney is thrilled she has finally got her pre-baby body. But we are really worried she might not be going about it in the healthiest way.

"This cycle of consuming fatty foods then starving herself must be playing havoc with her health. Britney looks fantastic in all her promotional pictures, but in reality she is a mess. Her skin is dull and blotchy and her hair is lank."
