Madonna reinventions 'weren't calculated'

Madonna has revealed that her style beginnings were never "calculated".

The popstar has said that her reason for constantly reinventing her image is because "it's boring to stay the same".

The 51-year-old told Rolling Stone: "I think people put a lot of emphasis on the whole reinvention of my image, and it’s always been a lot less calculated than people think.

"I think it’s boring to stay the same. A girl likes to change her look. But if she had to pick her worst fashion moment: It was the purple lipstick, fluorescent-green sweater combo... It’s OK, it was the Eighties. It was a bad-hairstyle era. Let’s face it."

Madonna recently admitted that she is sick of her old songs.
