Martin and his partner, according to a source close to the Puerto Rican daily, will wed in the U.S. city which last June 24 approved marriage between homosexual couples.
Since he announced his sexual orientation in March 2010, the artist, who on Dec. 24 turned 40, has expressed his support for marriage among people of the same sex.
He also said last June that he favors homosexual marriage in Puerto Rico, where it is still illegal.
"What I want is for them to say no to discrimination so that equality among us human beings may be a reality in my country," said Martin at that time.
Martin, who on Nov. 4 was granted Spanish citizenship, admitted he is gay on March 27, 2010, calling his homosexuality "a gift," on his Web page in a communique.
From that point on, the popular artist has participated in events supporting homosexuals, among them one last March in New York when he received the Vito Russo prize from Gay and Lesbian Alliance Against Defamation (GLAAD) for his promotion of rights equality for the gay community.
Martin took advantage of the event to confirm his much-speculated-about romantic relationship with Gonzalez.
"I only wanted to be free and I can say that today I'm free," said Martin at the event at which he especially thanked "my partner, my boyfriend, Carlos. You're the greatest."
