Ex-Gov. David Paterson tied the knot this weekend with Mary Sliwa at the luxe Water Club on the East River.

The ceremony was officiated by former Mayor David Dinkins, and the Rev. Al Sharpton stopped by to congratulate the couple, we’re told.

Sliwa, formerly married to Guardian Angels founder Curtis Sliwa, will take Paterson’s middle and last names, becoming Mary Alexander Paterson.

“She will now be my angel,” Paterson told us.

Her son toasted the couple, who met at Le Cirque in 2013 and began dating in 2015.

Curtis and Paterson used to have a radio show, “Curtis and the Gov.”
