Legendary fashion designer Diane von Furstenberg issued a stunning response when asked about her decision to marry a gay man.

The Belgian born-designer has married two non-heterosexual men in her life, which includes her current husband of 24 years, billionaire businessman Barry Diller.

Diane, 78, was being interviewed by Variety this week when she was asked, ‘What does it mean to be a woman married to a man who’s gay?’

Seemingly annoyed by the question, she responded, ‘What’s the difference? I don’t understand?’

Journalist Ramin Setoodeh pressed her further, stating, ‘A lot of women wouldn’t want to be married to a gay man.’

Diane shot back, ‘But 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.’

She also referred to Barry, who made his fortune founding the Fox Broadcasting with Rupert Murdoch, as her ‘soulmate.’

The designer’s first marriage was to Prince Egon von Furstenberg, the elder son of Prince Tassilo zu Fürstenberg.

Prince Egon was openly bisexual and was known for partying at notorious gay hotspot Fire Island.

Diane married the raunchy royal in 1969, but officially separated from him just three years later in 1972.

She met media mogul Barry in 1974 and the couple stayed together until 1981, then split.

They then reunited once again in 1991, but it wasn’t until 2001 that they finally decided to get married.

Barry previously wrote about his love affair with Diane in his memoir, Who Knew.

In the book, the 83-year-old admitted that Diane was the only woman that he’d ever been sexually attracted to.

‘While there have been a good many men in my life, there has only ever been one woman, and she didn’t come into my life until I was 33 years old,’ he wrote.

‘There are many complex aspects of my relationship with Diane von Fürstenberg: romantic love and deep respect, companionship and world adventuring, then disappointment and separation, and finally marriage.’

He continued, ‘I have never questioned my sexuality’s basic authority over my life (I was only afraid of the reaction of others). And 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?’

‘I’m well aware that this part of my life has caused confusion and lots of speculation. A relationship that began with indifference, then exploded into a romance as natural to us as breathing, surprised us and everyone else. It really is the miracle of my life.’

In the book, he also detailed an incident where he and Diane got caught having passionate sex in the music mogul David Geffen’s guesthouse in the early days of their relationship.

Prior to publishing his memoir, Barry had never come out publicly, although his sexuality was an open secret in Hollywood.

Diane previously told the Times of his revelation: ‘He’s been private all his life, but not with me. So for me, it doesn’t feel strange.’

‘All I can tell you is Barry and I have had an incredible life, love for 50 years. We have been lovers, friends, married, everything.

‘Today, he opened to the world,’ she added. ‘To me, he opened 50 years ago.’
