New York City Council Speaker Christine Quinn and her longtime partner, lawyer Kim Catullo, tied the knot on Saturday.

The ceremony, held in Chelsea, was attended by some of the biggest names in New York politics, including Governor Andrew Cuomo, New York City Mayor Michael Bloomberg and Senator Kirsten Gillibrand.

Judith Kaye, New York's former chief judge, officiated over the wedding.

“It's a historic moment in history that we are all celebrating now,” Gillibrand told NY1. “And our job is to make sure that we have equality for all, that every loving couple in America can celebrate publicly with the person that they love, with their family around them and with the blessing of their state.”

Cuomo, Bloomberg and Quinn strongly supported passage of New York's gay marriage law last year.

“When they attributed their marriage to New York law, there was a great round of applause, for the very special law that was passed that enabled this,” Congresswoman Carolyn Maloney told NY1.

Quinn is the presumed Democratic candidate for New York City mayor. If elected next year, she would become the city's first openly gay mayor. And the first legally married, openly gay politician to lead a major U.S. city.
