The Duke of Sussex wore a red poppy pinned to his lapel ahead of Remembrance Day

Meghan Markle and Prince Harry were among around 300 guests who attended Kris Jenner’s 70th birthday celebration at Jeff Bezos’s Beverly Hills estate on Saturday evening.

The reality television matriarch marked the milestone with a James Bond-themed party at the tech billionaire’s £130million home, chosen as a nod to her turning 70, with the “007” reference forming the basis of the theme.

Television cameras were not present at the event, and guests were reportedly informed that the gathering would be entirely private.

The Duke and Duchess of Sussex arrived together and were seen walking hand-in-hand into the venue.

Harry wore a black dinner jacket with a bow tie and a red poppy pinned to his lapel ahead of Remembrance Day.

His expression appeared serious as he made his way into the celebration. Meghan wore an elegant black ensemble consisting of a form-fitting top and a wrap-style skirt, smiling as she accompanied her husband.

Their appearance marked one of their most visible social outings in recent months, indicating that they remain connected within prominent American celebrity circles.

The couple have largely kept a lower public profile in recent weeks, concentrating on charitable work and media projects in California.

Ms Jenner made a dramatic entrance in a strapless scarlet gown featuring multiple ruffled tiers that extended into a long train.

She completed the look with black evening gloves, sparkling drop earrings and an updo hairstyle.

She was accompanied by her partner, Corey Gamble, who has been in a relationship with her since 2014.

Mr Gamble, 44, wore black trousers and a matching T-shirt, accessorising with gold jewellery including a cross pendant and bracelet. He carried an oversized bottle of wine as the pair joined guests.

Speculation has circulated suggesting that the birthday celebration could have doubled as a setting for a secret wedding for Ms Jenner and Mr Gamble.

These claims remain unverified, and no evidence has emerged from attendees to support the rumours.

The guest list, while understood to include high-profile figures from entertainment and business, has not been fully disclosed.

A musical performance reportedly took place during the evening, though the identity of the performer has not yet been revealed.

Ms Jenner’s decision to adopt a themed celebration follows her approach to previous milestone birthdays.

For her 60th, she hosted a party inspired by The Great Gatsby, drawing on 1920s glamour. The 007 motif for her 70th continued this pattern, using a familiar cultural reference to shape the tone for a carefully orchestrated evening.

The Sussexes’ attendance places them among a select group invited to one of the most high-profile social events in Los Angeles this season, reflecting the continued prominence of Ms Jenner’s social circle and the couple’s position within American celebrity society.
