Sir Elton John is not a happy rocket man. The legendary performer is slamming famed Domenico Dolce and Stefano Gabbana, who are gay and were previously in a relationship, after their controversial comments criticizing "gay adoptions" and IVF. 

"The only family is the traditional one," the pair told Italian magazine Panorama. "No chemical offsprings and rented uterus: life has a natural flow, there are things that should not be changed." The duo also referred to children of IVF "synthetic children."

Needless to say many proud parents who had to use IVF to have children are up in arms about the criticism -- namely Elton John and David Furnish, who have two sons via IVF. The over-the-top singer took to his Instagram to challenge the remarks. John posted a vintage pic of the fashion duo and wrote, "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 (sic)."

Ricky Martin, who has twin sons via a surrogate, wrote, "@dolcegabbana ur voices R 2powerfull 2B spreading so much h8. Wake up,Its 2015 Luv urselves guys," he wrote, before repeating John's "#boycottdolcegabbana instruction."

Tennis champ Martina Navratilova also was unhappy about what went down, writing on Twitter, "My D&G shirts are going in the bin - don't want ANYONE to wear them."

Wild woman Courtney Love 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."

Stefano Gabbana tried to backtrack after outrage erupted over his views. The fashion maker said"

"It was never our intention to judge other people's choices. We do believe in freedom and love.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."

"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."

What's really interesting about this whole debacle is that in 2006 Gabbana told an Italian newspaper in 2006 that he wanted to have a child via artificial insemination. The Italian said, "My dream is to have a baby, not to adopt one because I am not up to it and I don't feel strong enough. I want my own child, a biological child, the fruit of my sperm, conceived through artificial insemination because it wouldn't make sense for me to make love to a woman I don't love."

Wow! Umm we definitely think D&G should have stuck to doing what they do bet -- desinging clothes and sunbathing in St. Tropez -- instead of making insensitive comments.
