Robert F. Kennedy Jr. had a bizarre, self-absorbed response when news of his sexting affair with Olivia Nuzzi broke in the wake of his presidential campaign last year, the disgraced former DC correspondent reveals in her new book.

“If it’s just sex, I can survive it,” the married politician told her in September 2024 — in an apparent reference to his political career.

Nuzzi — an ex-New York Magazine political journalist who met Kennedy during his bid to become president — told him she would do whatever he needed her to do as the scandal broke, according to a New York Times profile, which previews parts of her book.

Kennedy, 71, is now US Health and Human Services secretary, and Nuzzi, 32, is an editor at Vanity Fair.

Her tell-all “American Canto,” which reveals details of the racy affair, is set to be released next month.

While Nuzzi’s book doesn’t directly address whether she had sex with Kennedy, she has denied it in the past.

“The relationship was never physical but should have been disclosed to prevent the appearance of a conflict,” Nuzzi said in a statement after their sexting was exposed last year.

“We were not sleeping together,” she later said in an interview, according to The Times. 

Through a spokesman in September 2024, Kennedy denied having an inappropriate relationship with Nuzzi.

He did not respond when The Post reached out to the Health and Human Services department. “I never comment on those kind of stories,” Kennedy said when asked about the affair on “The Story With Martha MacCallum.”

Kennedy suspended his presidential campaign in August 2024, saying he would endorse Donald Trump, several weeks before the scandal broke.
