Cheryl Hines is ‘no pushover,’ likely fuming over husband RFK Jr.’s alleged affair with star political reporter Olivia Nuzzi: source

“Curb Your Enthusiasm” star Cheryl Hines hasn’t publicly commented on hubby Robert F. Kennedy Jr.’s sexting scandal with a much younger political reporter — but she’s likely fuming behind the scenes, a source told Page Six Friday.

The source, who knows the couple, said Hines is no pushover at home and “has a backbone.”

“He was on the road a lot this year, so maybe it was different and tested the relationship,” the source speculated, referring to RFK’s quixotic presidential bid which was suspended last month.

“I don’t imagine her putting up with this. She has a backbone. She’s not a little housewife at home. She is successful financially independent on her own.”

News of the 70-year-old Kennedy’s alleged digital-only, sexting relationship with New York Magazine reporter Olivia Nuzzi, 31, broke Thursday, sending shockwaves through the DC circuit and beyond.

Hines and Kennedy, 70, have been married since 2014 — and celebrated their 10-year anniversary last month.

Nuzzi — who was recently engaged to Politico reporter Ryan Lizza — was placed on leave from the publication after the alleged affair came to light.

“She had engaged in a personal relationship with a former subject relevant to the 2024 campaign while she was reporting on the campaign, a violation of the magazine’s standards around conflicts of interest and disclosures,” New York Magazine said in a statement.

Nuzzi wrote about Kennedy for the magazine in the fall of 2023. The unlikely pair were believed to have started allegedly sexting around the new year, sources told The Post.

Nuzzi admitted in a statement of her own that, earlier this year, “the nature of some communications between myself and a former reporting subject turned personal” — without naming Kennedy. She insisted the relationship was never physical.

A rep for Kennedy, meanwhile, said the failed presidential candidate only met Nuzzi “once in his life for an interview she requested, which yielded a hit piece.”

But sources told The Post Friday that the two “weren’t being particularly careful” about keeping their tryst a secret.

“There’s a reason New York mag found out,” the source said.
