Cheryl Hines may divorce RFK Jr. — but it’ll be over Donald Trump more than Olivia Nuzzi

Cheryl Hines may divorce Robert F. Kennedy Jr. — but it’ll be over his relationship with Donald Trump more than his relationship with star New York Magazine writer Olivia Nuzzi, sources say.

Jerry Oppenheimer, the author of two Kennedy books including, “RFK Jr. and The Dark Side of the Dream,” wrote in the Daily Mail this week that Hines pals think the “Curb Your Enthusiasm” actress is going to end the ten-year marriage after being “blindsided” by the affair with Nuzzi.

“She’s thoroughly embarrassed and furious about his adulterous actions and they believe she wants out,” he writes.

And sources have told Page Six that Hines is, indeed, likely leave him. But a source tell us that Hines, a lifelong Democrat, is more upset by his newfound position in the MAGA universe than his digital dalliances.

“The guy is a serial philanderer and she knew that coming in,” shrugged our source.

But who could have have known when she wed the scion of America’s most famously Democrat family at their legendary compound in Hyannis Port he would one day drop out of the White House race to endorse the Republican presidential candidate — let alone Donald Trump. (It’s widely rumored that he made the move after being assured he would have a cabinet seat should Trump win in November).

“She knew she was getting in with a Kennedy who are known for being infamous womanizers,” says a source. “But she never signed up to be a member of Trump World!”

Hines distaste for the former President is no secret and Kennedy, a former Democrat, even told TMZ that she was uncomfortable about the endorsement.

“This is a really difficult issue for Cheryl,” he said. “This is the opposite of what she would want to do. She went along with it because she loves me and she wanted to be supportive of me, but it was not something that she ever encouraged. I would say, her trepidation about this and her discomfort with this, were the dominant feelings.”

A source told Page Six that there are some people in the Trump camp who “hate” Hines because of her politics and are actually hoping the Nuzzi scandal does split them up.

“There’s a likelihood he’ll work in the Trump administration if [Trump] wins,” said the source. “RFK Jr. would have to move to DC and they don’t want [Cheryl] around.”

News broke in mid September that RFK Jr., 70, and Nuzzi, 31, had started a texting relationship after she profiled him for New York Magazine. 

A source told Page Six the pair had “incredible” FaceTime sex and even said they loved one another. 

The messy scandal has turned into a very public back and forth with sources claiming Kennedy “love bombed” Nuzzi and that she was infatuated with him. 

Nuzzi has been placed on leave.

Kennedy has denied their affair and some close to him implied that he might sue her.

Hines, 59, was initially spotted in Milan without her wedding ring after the news broke. She has since made a point to show off the sparkler to photogs.

Oppenheimer’s sources told him that “Cheryl was always very aware that Bobby had a long history of womanizing. She herself had become very publicly involved with him when he was still married to his second wife, so his playing around wasn’t anything new to her.” 

“However, she firmly believed Bobby, in his seventh decade and with political aspirations, finally had his sex demons under control, and appeared settled down in their seemingly bucolic southern California domestic life.”

Kennedy’s philandering was well documented in three of his diaries exclusively seen by The Post after his second wife, Mary Richardson Kennedy, took her own life in 2012. In them, he talked about his “lust demons” — and kept a scorecard of his sexual conquests.

A source previously told Page Six that Hines is likely “fuming” over the Nuzzi sexting affair and that she is “no push over.”
