Sporty Spice said that she was apprehensive about being part of the reunited group because she was concerned that a return to the limelight would trigger the anorexia she suffered at the height of the band's fame.
She confessed that she never wanted to be on diet but in order to be the part of the all-girl band she had to be in the perfect shape.
"I'd always said I'd never do it. But I didn't want to miss out and have regrets. I also didn't want to be the person that stopped it being the complete five. I was scared I'd be the villain," the Daily Mail quoted her, as saying.
However, she added that she was very happy with her body.
"I'm happy with my body. I've reached a good place. I'm healthy but I like Guinness and crisps," she said.
