Ex-governor David Paterson will wed Mary Sliwa on Saturday at the luxe Water Club on the East River, Page Six has learned, in a ceremony to be officiated by former Mayor David Dinkins.

The guest list for the fête includes at least two major political donors, Republican John Catsimatidis and Democrat Jeff Greene. “We have people that are very much on both sides of the aisle and have very strong feelings,” Paterson tells us. “It’s a good thing to see that people of different ideologies can come hang out and appreciate the fact that two people fell in love and want to get married.”

Paterson says he and his new bride will honeymoon on the Jersey Shore. Referencing Fred Armisen’s impression of him on “Saturday Night Live,” in which the character would constantly trash talk the Garden State, Paterson tells us, “I want to come out and make amends.”

Back in May, Page Six reported that Paterson surprised Sliwa by proposing at his 65th birthday party. They have been dating since 2015, and a source told us at the time that they first met at a luncheon at Le Cirque in 2013. Sliwa was married to Guardian Angels founder Curtis Sliwa, with whom Paterson used to have a local AM radio show, “Curtis and the Gov.”
