As a notorious public-access TV star in the 1990s, curvaceous Linda Pendergraft stripped off her clothes and rambled on camera for hours about love, happiness and the unity of souls.

Twenty years later, the one-time New Age diva is under investigation for allegedly spewing hate speech at her Greenwich Village building super.

“You f—-t Muslim terrorist!” the super at her West 4th Street building says Pendergraft, 60, shouted when he accidentally bumped her as he mopped the lobby floor.

She allegedly then threatened to kill him and sue him, in that order.

“I’m going to slit your throat and sue you!” she screamed, the super, Sokol Hasag, 43, told cops hours after the bizarre, Dec. 8 confrontation.

The NYPD Bias Incident Investigation Unit is investigating the alleged threats, sources said.

But when The Post caught up with Pendergraft on Wednesday, the still vivacious former star of the Manhattan Neighborhood Network oddity “Our Soul: Journey to Know Thyself and Love” was denying everything.

Or mostly everything.

“I never threatened him,” she swore.

Still, she admitted, they did fight that day, after he accidentally bumped her as he mopped.

A recent flu shot had left her with a 102 fever, she explained of her bad mood.

“He called me a has-been fake,” she recalled.

She retaliated in kind.

“I said, ‘Remember, you’re moving trash for a living, not me.’”

But there were no threats or bias insults during their fight, Pendergraft insisted.

“I really don’t remember what happened,” she said. “But I wouldn’t threaten him. I said, ‘Eff-you motherf—er.’

“Then his boss came, and I lifted my shirt.”

Besides, “He’s so good-looking,” she said of the super.

“I would never call him a f—-t,” she said.

“Maybe I called him a maggot.”

In the interest of fairness and parity, The Post also sought the super’s side of the story.

“Other tenants are scared of her,” Hasag — a Muslim from Albania who has worked at the building for 12 years — told a reporter.

“She was calling me a f—-t, calling me a terrorist. She must have a problem,” he said.

“She’s cursed at me before and then apologized to me the next day,” he said.

“I don’t want anything to do with her. . . I saw her roommate the other day, and I said, ‘Lenny, I don’t know how you live with her.”

The roommate, Lenny DeRosa, declined to comment, and would not confirm Hasag’s claim that he, too, has been threatened by the former New Age stripper.

But Pendergraft herself easily ‘fessed to that, telling The Post, “Now I did have a fight with my roommate, and I did say, ‘I’ll bust you in the head with the mallet’ but I didn’t mean it.

“I would never hurt anybody,” she insisted.

“I show my anger,” she explained. “I worry about the ones who don’t show their anger.”
