Sarah Harding has tragically passed away on September 5, 2021, following a 12-month battle with breast cancer, and numerous friends have posted tributes to the star, one of which was Katie Price. Sarah, 39, had a close friendship with TV personality Katie Price, 43, and the two were in fact such good pals that the late Girls Aloud singer was actually a bridesmaid at former glamour model Katie's wedding to Peter Andre in 2005.
