Girls Aloud delivered an emotional tribute to their late bandmate Sarah Harding as they launched their much-anticipated reunion tour tonight in Dublin, Ireland. The pop group, comprising Cheryl, Nadine Coyle, Nicola Roberts, and Kimberley Walsh, had pledged that their first performances since 2013 would be a heartfelt celebration of Sarah, who tragically passed away at the age of 39 from breast cancer in 2021.
