The Spice Girl – who has previously battled the eating disorder bulimia – has been on an extreme exercise and diet regime in a bid to get in shape for the band’s upcoming world tour.

Friends of the singer are now worried she has gone too far after she shocked onlookers with her super-slim figure when the Spice Girls performed at the recent Victoria’s Secret Fashion Show.

A source told Star: ‘The main talking point was how skinny Geri had become. Victoria Beckham is always criticised about her weight, but she actually looked curvy compared to Geri.

‘With Geri’s history of eating disorders, any major weight loss is worrying. Up until now, she appeared to be embracing her curves and was happy to keep them, but she seems to be slipping back into her old habit of working out and dieting to extremes.

‘We’re sure she feels under pressure to look good standing next to the likes of Victoria, but she seems to be taking it too far.’

Since giving birth to her daughter Bluebell 18 months ago, Geri has made a conscious effect to regain her size ten figure.

However, since the band announced they were reforming in June she has put pressure on herself to become the slimmest Spice Girl.

Her regime reportedly includes running ten miles a week, training with weights, not eating after 6pm and soaking in an ice bath in a bid to tone up.
