Victoria Beckham has come out in support of Sir Elton John after he called for a boycott of Dolce and Gabbana, saying they labelled children born through IVF "synthetic".
The former Spice Girl's backing of Sir Elton comes almost a year after the Italian fashion giants said Beckham came to design ''after many, many, many different things'' and ranked her work on a par with high street stores.
Sir Elton, who has two children with his husband David Furnish, rebuked the pair for criticising same-sex families and the use of fertility treatment.
Beckham tweeted: "Sending love to Elton David Zachary Elijah & all the beautiful IVF babies x vb."
Other celebrities to voice their support include singer Ricky Martin, who tweeted: "dolcegabbana ur voices R 2powerfull 2B spreading so much h8."
He added: "Wake up,Its 2015 Luv urselves guys boycottdolcegabbana."
Courtney Love Cobain tweeted: "Just round up all my Dolce & Gabbana pieces, I want to burn them. I'm just beyond words and emotions. Boycott senseless bigotry! boycottD&G."
Former Czech-American tennis star Martina Navratilova, who married her gay partner in December, tweeted: " My D&G shirts are going in the bin- don't want ANYONE to wear them."
Matt Lucas tweeted: "Just read Dolce and Gabbana's weird, bigoted comments about raising kids. Ugh, those guys are so creepy. BoycottDolceAndGabbana."
Footballer Peter Crouch tweeted: "I'm now going to have to turn down the next ad campaign BoycottDolceGabbana."
Business partners Domenico Dolc e and Stefano Gabbana, who are both gay and were formerly a couple, have previously voiced their rejection of same-sex marriage, but in an interview with an Italian magazine at the weekend the remarks were extended to an objection to gay families.
Dolce told Panorama: "What I call children of chemistry don't convince me, synthetic children. Wombs for hire, choice from a catalogue. And then you have to explain to this child who is the mother. To procreate ought to be an act of love, today not even psychiatrists are ready to confront the effects of these experiments."
In a post on Instagram, Sir Elton 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."
Gabbana said in a statement: "It was never our intention to judge other people's choices. We do believe in freedom and love."
On Instagram he posted "Je Suis D&G", echoing the "Je Suis Charlie" slogan that was popular after the attack at the offices of Charlie Hebdo in Paris earlier this year.
One of his other posts was a statement with his name at the bottom which said: "We firmly believe in democracy and the fundamental principle of freedom of expression that upholds it.
"We talked about our way of seeing reality, but it was never our intention to judge other people's choices. We do believe in freedom and love."
In a post, with Dolce's name at the bottom, a statement said: "I'm Sicilian and I grew up in a traditional family, made up of a mother, a father and children.
"I am very well aware of the fact that there are other types of families and they are as legitimate as the one I've known.
"But in my personal experience, family had a different configuration. That is the place where I learnt the values of love and family.
"This is the reality in which I grew up, but it does not imply that I don't understand different ones.
"I was talking about my personal view, without judging other people's choices and decisions."
When asked at a fashion event in London last April what they thought of new designers such as Beckham, Gabbana said: ''She's a friend. She make a good job but ... for us, she don't make the same way like a fashion designer.
''She become after many, many, many different things. She's a designer but...''
When asked if he admired her designs, he said: ''She's a fashion designer but it's another ... it's different.''
He added: ''John Galliano is a designer ... Alexander McQueen.'' Dolce described them as ''professional'' designers, adding: ''Victoria Beckham, Zara, H&M ... there's a lot.''
In an interview in 2006, Gabbana revealed that he had approached a woman to be the mother of his baby but made it clear he struggled with the idea of a gay family.
"I am opposed to the idea of a child growing up with two gay parents," he said.
"A child needs a mother and a father. I could not imagine my childhood without my mother. I also believe that it is cruel to take a baby away from its mother."
The designers have put the traditional family at the centre of their last two collections, sending a pregnant model and women with their own children down the catwalk to celebrate motherhood for next winter's womenswear collection, while featuring grandmothers with their grandsons for menswear.
