Britney Spears' body has been transformed in the last few months, and according to The Daily Mail, it all has to do with Britney's much-hyped appearance on the British mega-hit, X Factor, this weekend. Tell us, what is Britney's secret!

"Friends of the star claim she is going to extreme measures to look in top shape for her first performance on British TV screens in five years....A source said: 'She goes to bed hungry and is dieting so hard she's suffering from insomnia, anxiety, flushes and shakes. 'Her father and the people around her are trying to get her to eat more, but Britney is determined not to be criticised for having any extra bulk.'"

Britney is a lunatic with an extreme personality, so of course proper diet and exercise wouldn't be the first thing that popped into her mind when she thought about losing weight. It was probably trying to find a carnival gypsy to curse her, but I guess she settled on starving herself. No need to worry, though. Either she gets super skinny or one of her walking hallucinations convinces her that a chainsaw is a microphone. It's a win-win, man. A win-win.

Starbucks is apparently still okay:
