Prince Harry and Elton John teamed up for a cause that is close to their hearts.

On Thursday, the prince and the award-winning musician launched a global coalition focused on treating HIV infections in men. John’s AIDS Foundation made the announcement, but they did not go into details about their plans.

Prince Harry and John’s work will be discussed thoroughly at the 2018 International AIDS Conference in Amsterdam on July 24. Both men are avid campaigners of HIV and AIDS, and they also share a close relationship with HIV advocate Princess Diana.

When the Princess of Wales passed away in 1997, John was asked to sing a song for her family and friends. He was also invited to Prince Harry and Meghan Markle’s royal wedding on May 19.

In a previous interview, John talked about his and Prince Harry’s work that is aimed at addressing HIV in men. He said that men are the only demographic where HIV rates are rising and not decreasing.

“Since then, my Foundation, along with other partners, have been undertaking participatory, human-centered design research collectively covering six countries. A critical finding from this work is the urgent need to rapidly scale up men’s access to and engagement in HIV testing and treatment services,” he said (via Daily Mail).

Last month, the “Candle In the Wind” singer also made headlines after he talked about Princess Diana and Prince Harry during an interview on “BBC Newsnight.”

“Harry has inherited his mother’s ability to walk into a room and make people, of any caste or any status in life, feel equal. That is an incredible gift. I’ve been around for 71 years and Princess Diana was one of the few people in my life who could do that. Harry has inherited that gift. He knows he has that gift. And that’s why he wants to do more with the AIDS community, the Commonwealth, and the youth,” he said (via Express).

During another interview, John also praised Princess Diana for all of her contributions to the HIV and AIDS community.

“One simple handshake, one gesture showed the world the desperate need for humanity for people living with AIDS,” he said.
