Olivia Nuzzi's forthcoming memoir will reportedly include salacious text messages between her and Secretary of Health and Human Services Robert F. Kennedy Jr.

The former New York Magazine reporter's memoir, entitled 'American Canto,' will delve into her relationship with Kennedy - and is said to be devastating for his wife, actress Cheryl Hines, Page Six reports.

'It's hard to imagine RFK surviving this with his marriage and job intact,' an unidentified source told the outlet.

The book will also reportedly get into her relationship with her ex-fiancée Ryan Lizza, which dissolved amid reports that Nuzzi had been 'emotionally involved' with the independent presidential candidate while writing a feature on his campaign.

Kennedy, 71, and his representatives denied any inappropriate relationship - claiming he met Nuzzi only once during an interview - sources described the connection as 'emotional and digital in nature, not physical.'

An internal investigation by New York Magazine found 'no inaccuracies nor evidence of bias' in Nuzzi's reporting on Kennedy, but the controversy nevertheless resulted in her departure from the publication.

She had served as the Washington correspondent for the magazine from 2017 to 2024, becoming well-known in the process for her coverage of political power players in Washington, D.C.

Her new book is now set to also delve into Nuzzi's decade covering President Donald Trump, along with information she pulled from hours of recorded interviews between herself and the president.

The information released in the memoir may be devastating for the Trump administration, as sources say there is concern for Nuzzi's safety as well as fear there could be an injunction or that the Trump White House could try to block the publication.

Simon & Schuster has even reportedly hired crisis PR expert Risa Heller, who previously worked with disgraced Congressman Anthony Weiner, as well as Jared Kushner and Jeff Zucker, to handle the rollout of the book.

But Nuzzi's affair has thus far seemed more devastating to the reporter than to Kennedy.

Not only did she lose her job, but her engagement to fellow journalist Ryan Lizza ended after the allegations came to light.

The former couple later became entangled in a contentious legal dispute, with Nuzzi accusing Lizza of threats and blackmail, claims she later withdrew.

He denied the allegations, calling them 'disgraceful lies' and part of a 'coordinated defamation campaign.'

Meanwhile, Hines publicly shrugged off the rumors.

She continued to appear publicly with him at major events, but reportedly declined to live in a Georgetown home the couple purchased, citing discomfort with the political spotlight.

When she was then asked about the rumors over the affair, Hines said she was not concerned.

'Lots of emotions with rumors! But, it will all be in my book. I'm writing a book. I've been taking notes -- serious notes,' the 60-year-old actress told US Weekly last year.

'People have a lot of feelings about politics, especially in Hollywood, and I don't know. I mean, so far I feel like it's OK.

'I'm OK to have conversations like that with people and, to me, it doesn't define somebody. To some people it does and it's like you can't control it. There's nothing I can do about it, so I have to let it wash over me.'

Hines's new book, 'Unscripted,' is set for release on November 11, and sources have said executives at Simon & Schuster have tried to keep Nuzzi's own memoir under wrap to avoid overlapping with Hines's book release.

They have said there are currently no preliminary copies of the tome for internal review, and the book is being kept on an entirely separate server to keep it secret.

An apparent Amazon listing for Nuzzi's memoir also has no image, no author and is listed as 'To Be Announced AC.'

It does, however, list a publication date of December 2, and provides users with the opportunity to pre-order the book - for $30 for a hardcover or $15 for an ebook.

The Daily Mail has reached out to Simon & Schuster, as well as the Department of Health and Human Services and a representative for Hines for comment.
