Kimberley Walsh has revealed how she and her former Girls Aloud bandmates have promised to honour the life and wishes of Sarah Harding.
Sarah died last September aged 39, just a year after being diagnosed with breast cancer.
And now Kimberley, Cheryl, Nicola Roberts and Nadine Coyle have announced they will take part in a Race For Life for Sarah in a bid to raise much-needed funds for research projects.
