DC bigwig Patricia Duff getting married for a 5th time despite swearing ‘she’d never get engaged again’

Beltway big Patricia Duff is going for No. 5!

The quadruple-married political fund-raiser, donor and activist is engaged again, Page Six hears — even though she said she’d quit the nuptials game.

The Dem honcho — who was previously hitched to billionaire financier Ron Perelman, Orion Pictures founder Mike Medavoy, DC attorney Daniel Duff and her high school sweetheart — “swore she’d never get engaged again,” an uptown insider told us.

“But, she’s giving it another go,” they added.

And — as if to underscore the point that she’s dated a fella or two in her time — the new beau is her second named Richard Cohen.

As Page Six reported at the time, Duff was in a long-term love match with Washington Post scribe Richard Cohen from about 2013 until about 2017.

But now we hear she’s betrothed to an entirely different Richard Cohen, this time the head of real estate firm Capital Properties.

(Cohen No. 2 is the ex-husband of onetime CNN anchor, Paula Zahn. The former couple made headlines of their own in 2007 after he found a diary in which Zahn had documented an affair she’d had, drawing heavily on the natural newswoman’s eye for evocative detail. They separated in a split rich with lawsuits.)

Reached for comment about her engagement and unexpected return to the marital fray, Duff — the founder of Common Good, which seeks to encourage citizens to take part in the democratic process — told us, “Let me just say: I never look back, just forward, to spending our lives together — happily.”

Of the Cohen/Cohen confluence, she said: “an amusing coincidence about someone who remains a good friend.”

Duff worked on the ill-fated Gary Hart presidential campaign, was a vocal supporter of Mike Bloomberg during his mayoral candidacy and also had an acting career in the ’80s, appearing in “Moonlighting” and in Rob Lowe, Demi Moore and Jim Belushi’s “About Last Night.”
