A world away from Royal duty: Prince Harry seems ‘fed up of being paraded’ and unable to ‘stage rictus grin’ as he and poppy-less Meghan visit Kris Jenner’s 70th on the eve of Remembrance Sunday

Prince Harry looked ‘tired of parading’ and failed to flash his ‘rictus’ smile as he attended Kris Jenner’s star-studded 70th birthday party, a royal expert told the Daily Mail.

The Duke of Sussex couldn’t help but smile as he walked hand-in-hand with his beaming wife, Meghan Markle, on their way to a James Bond-themed party in Beverly Hills.

Harry, 41, wore a stern expression as he strolled into Jeff Bezos’ $165 million mansion, a poppy pinned to his black tuxedo, rubbing shoulders with A-list stars and tech moguls.

Meanwhile, poppy Meghan, 44, was close behind, grinning from ear to ear in a tight black top and wrap skirt on the eve of Remembrance Sunday.

Royal author Tom Bower said getting an invite to Kardashian’s birthday party would be a ‘huge plus’ for Meghan.

But he said: “It is remarkable that Harry cannot fake the rictus smile that actress Meghan always displays for the cameras.”

He told the Daily Mail: ‘He seems fed up with parading around at a sporting event one day and a celebrity party the next.

‘Obviously, he’s now worried about what revenge his brother might one day take against him and his ambitious wife.’

Meanwhile, poppy Meghan, 44, was close behind, grinning from ear to ear in a tight black top and wrap skirt on the eve of Remembrance Sunday.

The Sussexes were “conspicuously” not invited to Bezos’ 60th birthday party, held near their Montecito home last year.

But Mr Bower said Meghan ‘ordered her staff to get invitations to big celebrity events’ because of her ‘desperation to get noticed’.

“The Duchess has now become a publicity-seeking guest rather than a guest for hire,” he said.

‘And this time he won a big party prize. It’s her first time meeting A-list celebrities. ‘This is a huge blow for a Duchess seeking security and approval.’

Eight years after leaving Hollywood, Meghan will return to acting in a new film alongside Lily Collins, Brie Larson and Jack Quaid.

The mother of two is reportedly playing herself in the movie Close Personal Friends, which is about two couples, one famous and the other not.

This week he was spotted on set in Pasadena, Los Angeles at the Amazon MGM Studios production.

Meghan Markle is returning to her acting roots by filming a scene for the upcoming movie Close Personal Friends in Pasadena, California.

It was seen as a ‘tremendous moment’ for Meghan, with Harry being ‘really supportive’ and wanting his wife to ‘do anything that brings her joy’.

Star guests invited to Kris’ party included Mark Zuckerberg, Mariah Carey, Justin Bieber and Snoop Dogg, while the Sussexes also had the chance to reunite with Oprah Winfrey, who arrived with her long-time friend and TV presenter Gayle King.

He and Oprah were seen sitting side by side in the backseat of the event as they headed to the party shoulder to shoulder with showbiz dignitaries.

Among them was Adele, whose diminutive body was on sizzling display as she emerged from her car in a brocade black dress with lace sleeves.

Kim Kardashian, who just passed the bar exam, shook herself up and dazzled for a night out in a dark purple dress.

The clingy backless number allowed her to show off her world-famous curves to full advantage as she made her way to her mum’s fabulous bash.

Kris’ first child, Kourtney Kardashian, modeled an outfit consisting of sheer black opera gloves with a new tasseled hairstyle.

Kylie Jenner – Kris’s youngest – wore a chic 1960s sleeveless turtleneck white dress with a slicked-back hairstyle to match.

Kris herself was also spotted arriving at Bezos’ mansion, going all out for a luxurious look.

She wore a strapless crimson dress and was adorned with a billowing skirt that featured cascading rows of ruffles that culminated in a train.

Wearing her dark hair into a bun that highlighted her dazzling drop earrings, the reality TV matriarch added extra-glam black opera gloves.

One of the superstars sprinkled throughout the guest list was none other than Mariah Carey, who wore a gold gown adorned with shiny metallic details.

Kim Kardashian wore a backless number that allowed her to show off her world-famous curves to full advantage as she made her way to her mom’s gorgeous bash.

Snoop Dogg, meanwhile, wore a three-piece suit and bow tie, along with trendy shades and a clutch bag.

Jeff Bezos’ tech boss Mark Zuckerberg was also seen arriving at the party

Justin Bieber ditched his usual loose-fitting clothes and showed up in a stylish black suit, even putting a pink flower on his lapel.

Her longtime toy boy, Corey Gamble, 44, arrived dressed much more casually in a black T-shirt and matching pants, a jumbo-sized bottle of wine in hand.

Her simple outfit was adorned with jewellery, including a sparkling bracelet along with a gold watch and what appeared to be a matching cross.

A wild unsubstantiated claim emerged via TMZ on Friday that Kris and Corey used her 70th birthday as bait for a surprise wedding following their 11-year romance.

Kris and her four daughters – Kim Kardashian, Khloe Kardashian, Kylie Jenner and Kendall Jenner – were guests at Jeff and Lauren’s star wedding this summer.

The Daily Mail has contacted Sussex’s representatives for comment.
