Fashion designer Diane von Furstenberg is speaking out after her husband of 24 years, Barry Diller, publicly came out as gay. "What's the difference? I don't understand," von Furstenberg, 78, told Variety in a Thursday, October 16, profile, when asked about being married to a gay man. "It doesn't change anything. I'm sorry - it's a stupid question. I married two gay men, OK? I don't know why, but to me, they're not gay, so it doesn't make any difference." The fashion icon has been married twice. She was married to the late Prince Egon von Fürstenberg, who was openly bisexual, from 1969 to 1983. (Diane and Egon, who died in 2004 at the age of 54, shared two children.) After their divorce, Diane moved on with Diller, now 83, and they tied the knot in 2001. Diane addressed Diller's admission after he publicly disclosed his sexuality in a New York Magazine essay published in May, noting that there are "many complex aspects" in their marriage.

"When my romance with Diane began, I never questioned that its biological imperative was as strong in its heterosexuality as its opposite had been. When it happened, my initial response was 'Who knew?'" He continued, "Even though as the years went on, I began to be realistic and understood that 'everyone knows,' I never wanted to make any declarations. Of course I could have declared my sexuality, come out as some others were doing, but I was among the many at that time who were too scared to do so." Diller also explained how his sexual orientation affected his relationship with Diane. "We weren't just friends. We aren't just friends. Plain and simple, it was an explosion of passion that kept up for years," he wrote. "And, yes, I also liked guys, but that was not a conflict with my love for Diane. I can't explain it to myself or to the world."

"Supporting him? What do you mean, supporting him? People see it that way. For me, it's not that way. I don't know," Diane told Variety. "Yes, I encouraged him to do that book, and yes, I encouraged him to do the Audible [version]. But for me, the book is not about that. It's about his life, and of course, with me, he opened immediately. For 50 years, I was the only person he opened [up] to, then he wrote the book." Diane and Diller dated on and off from 1981 to 1991, before getting married 10 years later. As Diller noted in his New York profile, the pair have spent their 50-year relationship in "a unique and complete love." "We weren't particularly conventional characters, and were so demonstrably in love both inside and outside the house," he added at the time. "We were, though, still the subject of interest and gossip from people in the film and fashion worlds. But we were mostly oblivious to anything other than being together. Well, maybe we did prance a bit, enjoying the attention."
