Mexican singer Margo Rey has signed on as the ambassador of Brides Against Breast Cancer as she battles the disease.

The Let the Rain hitmaker, who is set to become a bride this autumn (13) when she marries her comedian fiance Ron White, has teamed up with charity bosses to shoot a new campaign for the organisation, which helps raise money for patients and their families.

Rey says, "From my perspective as a breast cancer warrior now undergoing chemotherapy, I believe that education and personal support are just as critical as prompt medical treatment. It is my pleasure to join Brides Against Breast Cancer to raise awareness and help ensure that no one ever has to face cancer alone."
