"She was there for her as a friend and supportive voice," Jake Glaser, now 37, says of the sweet bond Princess Diana formed with the HIV/AIDS advocate.
Princess Diana was known for her HIV/AIDS advocacy on the world stage, but her support didn't stop behind the scenes — especially when it came to her friendship with Elizabeth Glaser, who died of AIDS in 1994.
"Diana called my mom often in the last year of her life," Jake Glaser, Elizabeth's son, tells PEOPLE in this week's issue before World Aids Day on Dec.
"The strongest parallel between Princess Diana and my mother was definitely their love and advocacy for children," says Jake.
The memory of that day is captured in a photograph of Diana, Elizabeth, Paul, Jake and Glaser family friend Ann Jordan.
"Even after that photo was taken," says Jake, Diana's calls to Elizabeth continued.
Three years earlier, Elizabeth died at the age of 47 — but both her and Diana's passion for advocacy lives on in their children.
