City Council speaker Christine Quinn will tie to knot today in New York City during a private ceremony among 300 family and friends.

The occasion marks the first same sex wedding for a high-ranking city official since New York legalized gay marriage last year.

Quinn, a proud Irish American and 2013 mayoral candidate, will marry her longtime partner Kim Catullo, a corporate lawyer whom she met on a blind date in September 2011.

City officials attending include Mayor Michael Bloomberg, Governor Andrew Cuomo, and senators Kirsten Gillibrand and Charles Schumer.

During a press conference earlier this week Quinn told reporters that President Barack Obama is “more than invited to the wedding.”

“I’m nervous I’m going to trip on my heels, I’m nervous that the vows will stink, I’m nervous that they’ll make the dress too tight and I won’t be able to sit down or dance, worried that we sat somebody next to somebody that we didn’t know hated each other and there’s going to be a big drama,” Quinn said.

The elected official said she was moved by all the well-wish from people.

“People at the senior centers have been saying congratulations and like a good elected official I’ll go, ‘Thank you very much.’ Then I walk out and say to the staff, ‘Why are they congratulating me?’ and they’ll say, ‘Cause you’re engaged!” Quinn said.

While the details of the wedding remain covert, some information has been leaked in the last few days.

Saturday's event will be held at Stage D at Highline Stages in Manhattan’s Meatpacking district, a venue which often plays host to Fashion Week shows.

Guests will enjoy a five-tiered chocolate chip and mousse cake from New Jersey’s Chocolate Carousel Bakery, which is owned by Catullo’s old college roommate.

DNA Info reports that in lieu of gifts the couple have asked their guests to make donations to the Memorial Sloan-Kettering Cancer Center in honor of their mothers, who both died from breast cancer when their daughters were in their teens.

Speaking on WOR-AM, Quinn said she would be wearing a bridal gown.

“I’m a little bit feeling like I’m 22-years old again, running around trying excessive number of dresses on,” Quinn said.

"It’s been great fun picking out dresses for the flower girls and all of that kind of stuff you think of when you’re a little girl, and for some of us, we felt would never get to happen," Quinn said.
