A dominatrix has revealed how Hollywood insiders get their kinky kicks without getting caught.

“Mistress Scarlett,” aka Jenny Nordbak, tells Page Six that dozens of members of LA’s creative class — from household-name musicians to famous screenwriters and even A-list actors — have hired her to whip, beat and bind them, and play out their fantasies.

Nordbak, who’s hung up her spikes and will publish a memoir, “The Scarlett Letters,” in April, says, “When you’re at the more exclusive private fetish play parties, that’s [when] you start to see more [famous people], and I did see more celebrities in that sphere.”

But braver “submissives” — including “a mega-famous actor,” whom “most women, and I’m sure a few men, have fantasized about kissing” — ventured to her dungeon.

Of that star, whose “magnificent” unmentionables almost made her break character, Nordbak dishes that he paid her to yank on strings attached to a certain private piercing.

Another client was a Hollywood screenwriter.

“He just had these super-elaborate, over-the-top, detailed scenes that he would want to play out … that was fun because you don’t usually get that amount of imagination,” said Nordbak. “He’s like, ‘I am the maharaja!’ and he’s in full costume; like a whole production.”

The USC grad added that “particularly with celebrities, they’re surrounded by ‘yes’ men and everyone is so in awe of them, and they don’t hear ‘no’ very often. So I think they’re so used to being the one with the power that surrendering that power to someone else is really exhilarating.”
