A “Real Housewives of London” star almost became a royal pain.

In a trailer for Hayu’s new reality show released Tuesday, cast member Panthea Parker, 50, prepared to meet King Charles at Buckingham Palace and planned to grill him about Prince Harry and Meghan Markle.

“I’m going to go up to the King, I’m going to go, ‘How do you feel about Harry and what he did?’” she told her husband, Ed Parker. In the clip, the couple appeared to be heading to a Buckingham Palace garden party, which they attended in May.

Reading a pamphlet, the British lawyer immediately responded, “It says, specifically, ‘Don’t ask the monarch about Harry and Meghan.’”

Although the royal family is known for upholding a strict protocol, Ed appeared to be joking about the specific instructions.

It is widely known, however, that the royal family’s ongoing rift is a sore subject.

Panthea is no stranger to high society. She is known to be part of the exclusive Mayfair scene and is friends with Jennifer Lopez.

The Iranian-born socialite also recently snagged an invite to 10 Downing Street, where prime minister Keir Starmer, lives according to the Hollywood Reporter.

“The Real Housewives of London” is set to premiere in the UK on Hayu on Aug. 18. The series does not currently have a US premiere date.

The feud between Prince Harry and King Charles began in January 2020 when Harry and Markle quit the royal family and moved to North America.

Things only worsened between the relatives when the 40-year-old and the “Suits” alum, 43, accused the royal family of racism and released a Netflix series about their issues.

In January 2023, the military veteran dropped his bombshell memoir, “Spare,” in which he alleged that William physically attacked him over Markle.

Harry said he was willing to “reconcile” with his family in May but acknowledged that “some members” of his family would “never forgive” him for “lots of things.”

On Sunday, it was reported that Prince Harry and King Charles’ aides met for “secret peace summit” in London last week after years of feuding.

The Mail on Sunday obtained photos of Meredith Maines, the chief communications officer for Harry and Markle, meeting with Charles’ communications secretary, Tobyn Andreae, last Wednesday.

“There’s a long road ahead, but a channel of communication is now open for the first time in years,” a source told the outlet.

“There was no formal agenda, just casual drinks. There were things both sides wanted to talk about.”

The insider added that the meeting was only the “first step towards reconciliation between Harry and his father, but at least it is a step in the right direction.”
