Singer Ricky Martin has warned Spanish conservatives against repealing the nation's gay marriage law.

Martin, who was granted Spanish citizenship four months ago, made his comments in a cover story for the April issue of the Spanish edition of Vanity Fair.

The story features photos of Martin posing for the first time with his twin sons, Matteo and Valentino, and boyfriend Carlos Gonzalez.

The recent election of Prime Minister Mariano Rajoy and his conservative Popular Party (PP) threatens the nation's gay marriage law, which was approved in 2005 by the Socialist government of Jose Louis Rodriguez Zapatero. The PP filled a legal challenge to the law based on technical grounds. Spain's Constitutional Court is expected to issue a ruling any day now.

“If they touch” that legislation, Martin said, “now, as a Spanish citizen, I would stand up and unite with my community.”

Martin also described how he selected the surrogate mother for his sons.

“I saw the photo and I said to myself: Who is this woman, so angelic, so transparent? I did not rent a womb. The fundamental conservatives use that expression. They loaned me an abdomen. I didn't pay for it,” he said. “I would give my life for the woman who helped me bring my sons into the world.”
