Victoria Beckham has joined Courtney Love, Ricky Martin and other stars in backing Elton John after fashion designers Domenico Dolce and Stefano Gabbana criticized same-gender couples having children and the use of IVF fertility treatment.

Elton John, who has two sons with David Furnish through a surrogate, posted on Instagram that everyone should boycott Dolce and Gabbana following the comments.

It wasn’t long until the #BoycottDolceGabbana hashtag was trending on Twitter.

Victoria Beckham tweeted: “Sending love to Elton David Zachary Elijah & all the beautiful IVF babies x vb.”

In an interview with Italian magazine Panorama the fashion designers said they didn’t agree with the idea of gay families.

Domenico 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.”

Ricky Martin, who has 6-year-old twins Matteo and Valentino born via a surrogate, also backed Elton John campaign.

People with children born through IVF have also joined the campaign posting family pictures across social media.

Stefano Gabbana has now said “it was never our intention to judge other people’s choice”.

“We do believe in freedom and love,” Stefano Gabbana added.
