New York - Madonna added her voice to the controversy surrounding fashion designers Domenico Dolce and Stefano Gabbana, telling them to "think before you speak" after Dolce described children born to gay couples through fertility treatment as "synthetic."
The performer joined other celebrities who criticized the Italian duo when she posted a message on Instagram along with a photograph of herself and a baby from Dolce & Gabbana's 2010/2011 winter collection campaign.
