Britney Spears’ comeback may be in jeopardy now that the pop star has adopted a diet of high-calorie junk food.

“Britney’s been eating burgers and chips for lunch in complete defiance of the strict eating plan worked out for her,” an insider revealed to Britain’s Daily Mirror on Wednesday.

The “Womanizer” hitmaker has reportedly refused to adhere to the 1,200 calorie a day pre-tour diet recommended by her trainers and managers.

“It’s as if she’s trying to defy her father and bosses, and break out of the controlled environment by turning away from the healthy lifestyle they’ve put in place.”

“Every decision in her life is made for her and she’s kept under the strictest watch to make sure her comeback is a success. Eating her favorite foods is one of the few ways she can control things.”
