Disgraced ex-Gov. Eliot Spitzer grimly refused Thursday evening to discuss allegations he engages in sexual fetishes that include hiring “young girls” to lead him around on a leash like a dog.

The infamous “Luv Gov” — who quit his job as the state’s chief executive amid a hooker scandal in 2008 — frowned and set his jaw when he encountered a Post reporter outside his swank Upper East Side apartment building around 6:15 p.m.

Spitzer, 58, was stone-faced as he ignored questions about his alleged leash kink while striding though the auto-opening front doors of 800 Fifth Ave.

Spitzer — whose long-suffering wife, Silda Wall Spitzer, finally dumped him in 2013 — recently put a three-bedroom, 22nd-floor apartment he owns there up for rent.

It’s on the market for $19,500 a month, but he’s living in another, even-plusher pad in the building, across the street from Central Park, a source there said.

On Wednesday night, The Post exclusively revealed that former escort Svetlana Travis Zhakarova, 27, filed papers in Manhattan Supreme Court to lift a gag order imposed during her prosecution on charges that included extorting $400,000 from Spitzer.

The Russian native claims she has a First Amendment right to “discuss any and all actions or events that she participated in with Spitzer.”

“Moreover, the fact that Spitzer was paying young girls to insert sex toys into his anal cavity and walk him around the floor on all fours with a leash is conduct that he made a conscious choice to engage in,” wrote her lawyer, Joseph Murray.

Zhakarova was sentenced in October to time served after plea bargaining to attempted petit larceny for trying to steal rent money from another older ex-lover, toy-store owner Paul Nippes.

Spitzer’s spokeswoman has called Zakharova’s allegations against him “reprehensible lies from an extortionist” and said “the record in this case and her guilty plea speak for themselves.”
