Elton John applauded Prince Harry for his live HIV test which was broadcast on social media to raise awareness about the deadly virus.
The 69-year-old singer spoke out about his appreciation of the prince's act via Instagram.
@eltonjohn: In 1991, Princess Diana moved a mountain by addressing the stigma surrounding people living with HIV/AIDS. She showed the world we could safely wrap our arms around AIDS patients, by shaking hands with a patient without gloves. We've made huge strides since then in the treatment of the disease.
People now live long, happy lives with HIV, when the virus is effectively managed with anti-retrovirals. Despite this amazing progress, most people today are still frightened and stigmatised at the notion of taking an HIV test.
Today in London, Prince Harry gave that stigma a knock on the head by showing the world how easy and simple it is to take an HIV test.
Bravo Prince Harry! Your mother would be so proud of you.
