Karl Lagerfeld and Alexa ChungKarl Lagerfeld with Alexa ChungKarl Lagerfeld's no stranger to controversy.

The German fashion designer has always been outspoken.

And now he's confessed to his use of high-class escorts.

In a frank interview with Vice magazine, the 78-year-old creative director for Chanel admitted: "I admire porn... And I personally only like high-class escorts.

"I don’t like sleeping with people I really love. I don’t want to sleep with them because sex cannot last, but affection can last forever.

"I think this is healthy. And for the way the rich live, this is possible.

"But the other world, I think they need porn.

He also repeated his opinion that gay marriage is wrong, saying: "Yes, I’m against it for a very simple reason: in the 60s they all said we had the right to the difference.

"And now, suddenly, they want a bourgeois life."

Karl might be upfront about his sex life, but there are many stars who'd rather keep things under wraps.
