Dolce & Gabbana have not only enraged gays and the parents of test-tube babies — now the fashion-designing duo is also being boycotted by feminists who are outraged by a fashion ad depicting what looks like a très chic gang bang.

Three bored hunks look on as a shirtless fourth man pins down a lithe model — wearing a swimsuit and high heels — who is arching her back.

“I guess simulating gangbangs are fine — but IVF and same-sex marriage are not — life according to @dolcegabbana,” fashion publicist Kelly Cutrone tweeted on Sunday.

Cutrone, in Los Angeles to tape another season of “America’s Top Model,” added, “Wish I were home so I could make a video of myself cutting up my @dolcegabbana clothes.”

The Italian designers — who are also against same-sex marriage despite 23 years as a gay couple — sparked a firestorm last week by calling IVF offspring “synthetic children” in Panorama magazine.

Elton John, Al Roker, Ricky Martin and hosts of other parents who used in vitro fertilization blasted the fashionistas.

“These guys are destructive,” Cutrone told me. “You can’t tell someone they are a synthetic human being.”

Cutrone said that when she saw the disturbing ad, “I literally was in shock. I thought, ‘Holy f–k, these guys are crazy. These guys are against IVF, but they are for gang bangs.”

Cutrone, the mother of a 13-year-old daughter, said thousands of people responded to her tweets, saying they had joined the boycott.
