When you're Kris Jenner turning 70, you don't just throw a party. You throw a James Bond-themed extravaganza at Jeff Bezos' mansion with enough billionaire firepower to make a Fortune 500 summit jealous. The "Kris 0070" celebration last weekend pulled in at least nine billionaires whose combined net worth clocks in around $600 billion, proving that the Kardashian-Jenner orbit isn't just about reality TV anymore.

Here's who made the guest list, according to Forbes.

The Tech Billionaire Contingent

Jeff Bezos himself played host, opening up his $165 million Beverly Hills estate for the evening. With an estimated net worth of $258 billion, the Amazon founder clearly has the space for this kind of gathering. The Bezos and Jenner families have maintained a friendship over the years, and Kim Kardashian attended Bezos' Venice wedding earlier this year, so the connection runs deeper than you might think.

Mark Zuckerberg showed up with his wife Priscilla Chan, bringing his $216.7 billion net worth along for the ride. The Facebook co-founder posed for photos with Jenner and even shared a selfie wearing a "Kim is my lawyer" hoodie, which is the kind of detail you couldn't make up if you tried.

Bill Gates, worth an estimated $103 billion according to Forbes, arrived gift in hand. The Microsoft co-founder has recently invested in an AI-powered shopping tool created by his daughter Phoebe Gates, with Kardashian serving as a mentor for the project. When billionaires network, apparently everyone benefits.

Snap CEO Evan Spiegel and his wife Miranda Kerr also attended, despite a past social media dust-up involving Kylie Jenner. With an estimated net worth of $2.7 billion, Spiegel proved that sometimes you just let bygones be bygones when the invitation comes.

Entertainment Industry Wealth

Michael Rubin, the Fanatics founder and CEO worth an estimated $9.6 billion, has become something of a regular in Kardashian-Jenner circles. Forbes notes he maintains friendships with Kim, Khloé, and Kendall, who frequently turn up at his famous Fourth of July parties.

Oprah Winfrey brought her friend Gayle King to the celebration. With a net worth Forbes pegs at $3.2 billion, Oprah's attendance makes sense given that she, Jenner, and King recently vacationed together in Spain. The friendships here aren't just for show.

Jay-Z arrived with Beyoncé and her mother Tina Knowles, adding his $2.5 billion fortune to the evening's tally. The hip-hop mogul and his family have maintained longstanding ties with Jenner over the years.

Tyler Perry, worth $1.4 billion, rounded out the entertainment billionaires. The filmmaker and actor has a history with the Kardashian family that goes back to casting Kim in his 2013 film "Temptation: Confessions of a Marriage Counselor," according to Forbes.

The Family Billionaire

Naturally, Kim Kardashian was there—she's Jenner's daughter, after all. But she also happens to be the family's sole billionaire, with Forbes estimating her net worth at $1.7 billion. Most of that wealth stems from Skims, her shapewear brand that hit a $4 billion valuation in a 2023 funding round. Not bad for someone who started out as Paris Hilton's closet organizer.

Beyond the Billionaires

The party wasn't exclusively a billionaire club. Media reports indicate that Meghan Markle and Prince Harry attended, along with Mariah Carey, Martha Stewart, Paris Hilton, Justin Bieber, Alicia Keys, Ciara, and Chris Rock. Bruno Mars performed during the evening, and the mansion was draped in red décor to match the casino royale theme.

Birthday parties are typically private affairs, but this one offered something unusual: a window into how pop culture influence and extraordinary wealth have become completely intertwined. When nine billionaires show up to celebrate someone whose fame originally came from a reality show, it says something about how much the lines between entertainment and business power have blurred. The Jenner-Kardashian family has built something that goes well beyond television—they've created a gravitational pull that draws in some of the world's wealthiest people.

And apparently, they all know how to dress for a Bond theme.
