"I'll mourn forever the loss of my friend. A true genius in not only fashion but in his heart," she wrote. "He was a king and had the highest standards of design and work ethic. He was so giving, so loving, his heart so full and pure."

Gaga claimed, "No one knew a woman's body like him", adding, "He should be celebrated as one of the greatest fashion designers the world has ever known."
