Stefano Gabbanna has responded to Elton John's calls for people to boycott the Dolce & Gabbanna (D&G) fashion label, insisting it was never "their intention to judge".
In an interview with Italian magazine Panorama, Domenico Dolce and Stefano Gabbana described children born through the process of IVF as 'synthetic'.
On Instagram, Sir Elton John, who has two children with husband David Furnish, said: "How dare you refer to my beautiful children as 'synthetic'.
"And shame on you for wagging your judgemental little fingers at IVF - a miracle that has allowed legions of loving people, both straight and gay, to fulfil their dream of having children.
"Your archaic thinking is out of step with the times, just like your fashions.
"I shall never wear Dolce and Gabbana ever again. #BoycottDolceGabbana."
But Stefano Gabbanna said "it was never our intention to judge other people's choices".
"We do believe in freedom and love," he added in a statement.
As well as business partners, Dolce & Gabbanna were in a relationship for 23 years before splitting in 2005. They had previously rejected same-sex marriage.
In the interview with Panorama, they said: "We oppose gay adoptions...The only family is the traditional one.
"No chemical offsprings and rented uterus: life has a natural flow, there are things that should not be changed."
Dolce said: "You are born to a mother and a father - or at least that's how it should be.
"I call children of chemistry, synthetic children. Rented uterus, semen chosen from a catalogue."
Stefano Gabbana added: "The family is not a fad. In it there is a supernatural sense of belonging."
