A-list US celebrity takes swipe at Prince Harry questioning his loyalty to the UK

Ms Vanderpump talked about Harry and Meghan Markle with American actor and TV host Jerry O'Connell, who noted that his wife, Rebecca Romijn, had recently flown on a plane with the duke.

Mr O'Connell stated: "My wife said, 'Yeah, it was exciting, [but] not as exciting [as] when Lisa Vanderpump sat two rows back'."

The Real Housewives star responded: "Well, I'm a loyal Brit. He isn't, right? Come on, you know, I'm telling the truth."

Ms Vanderpump grew up in the UK before moving to America, opening up a series of restaurants with her husband, Ken Todd.

The Duke and Duchess of Sussex also made the move overseas in 2020, moving to California after departing Frogmore Cottage.

Ms Vanderpump, who works in Las Vegas, said: "I love Vegas. I think it's the playground of the world, and growing up in London, in a suburb, when you'd come to Vegas, you'd never see anything like it.

"I still think it's like that. It's innovative, it's moving forward, I feel safe here [and] it's got this incredible energy."

The 65-year-old was a star of The Real Housewives of Beverly Hills for its first nine seasons, but now fronts her own spin-off, Vanderpump Rules.

The remarks from Ms Vanderpump come as the Duke and Duchess of Sussex attended the Kardashian-Jenner matriarch's 70th birthday, held at Jeff Bezos's $165million (£125million) mansion in Beverly Hills.

Harry stepped into a "protective role", acting like Meghan's "personal bodyguard" who appeared "coy" among A-list celebrities.

The duke led the Sussexes into the venue, walking slightly ahead of Meghan, who arrived with a gleeful smile.

UK body language expert Judi James explained that the prince wanted to protect his wife from paparazzi, taking a serious approach.

They told the Daily Mail: "In star terms, this reflects her return to the big screen as an actress, while he seems to be back in 'Spare' mode here.

"Harry's expressionless mode directs the attention to his wife here, although his ritual is one favored by the likes of Travis Kelce, with the outstretched arm held behind and away from his torso to suggest muscle power, and with his hand gripped around Meghan's in a similar 'Big Paw' Travis grasp that speaks of a desire to protect as they go past the press."

The expert discussed Meghan's recent announcement about her return to acting, where she will play herself in an upcoming Hollywood movie.

Ms James explained that when entering the event, Meghan strolled in with confidence, knowing she was a "big star".

The body language expert said: "There are several rankings of A-list body language behaviour on arrival at a venue or party, and they vary between the Kim Kardashian 'Solo Goddess' camera-friendly look to an Adele 'hiding my face with my bag' pose that suggests she's too cool and famous to need the publicity.

"A cut-off ritual like the lowered and hidden eyes suggests a coy lack of need to perform for the cameras, and it implies an assumption of rabid press interest rather than a courting of it. But Meghan also performs a smile of utter delight here. Her cheeks are rounded, and her lips are hiked up high at the corners to create a symmetric shape.

"A smile like this will be an acknowledgement to the fans and the cameras, but without any posing effort or showboating."
