A tired-looking Cole was wearing her wedding ring, which she only recently took to sporting again since reports her footballer husband Ashley Cole had an affair first cropped up in January.

In the group's upcoming autobiography Dreams That Glitter, Cole pledges to always work at her marriage and admits she has been left emotionally scarred.

She said: 'I can't hurt any more than I've been hurt, I can't cry any more than I've cried. I've been to the highest of highs and the lowest of lows, so one day I'm going to find my middle ground and be happy.'

Harding, meanwhile, hits out at her reputation for being promiscuous in the new book.

She said: 'One paper called me the "slapper" of the band. I don't think so. I've never even had a one-night stand.

'I have lots of male friends but that doesn't mean I'm linked romantically with all of them.'
