Sheer number of celebrities at Kris Jenner's 70th birthday party is blowing people's minds

If you're wondering where all of Hollywood's A-listers were on Saturday night, you'll have found a large majority of them at Kris Jenner's birthday party.

Jenner, the matriarch of the Kardashian/Jenner family, celebrated her 70th birthday on November 5 and, of course, threw a lavish soirée to mark the occasion.

The Los Angeles-based party was James Bond-themed and planned by Mindy Weiss. And it's safe to say that they went all out with the guest list, with famous faces from almost every industry being present and, of course, her superstar family members.

Where was the party held, I hear you ask? Jeff Bezos' Beverly Hills mansion, of course.

Bezos and his wife, Lauren Sanchez, were obviously in attendance with this in mind, as well as the likes of Bill Gates and Mark Zuckerberg.

Music icons like Mariah Carey, Snoop Dogg, and Adele were spotted at the star-studded bash as well.

Elsewhere, Kim Kardashian's All's Fair co-star Naomi Watts and Sarah Paulson (a series which debuted with 0 percent on Rotten Tomatoes) were on hand to mark Jenner's milestone birthday.

Here are some of the biggest names that were invited...

People have since reacted the Jenner's A-list guest list online.

"The guests range. Only Kris can pull this off," one person said. A second added: "Kris contact list goes CRAZY."

"Kris is a well CONNECTED," echoed someone else, as another person compared Jenner's birthday bash to the Met Gala.

Somebody else pointed out: "NOT 1 but 2 BILLIONAIRES!!"

"I am dying to know what gift does Bill Gates give to Kris Jenner," a different person wanted to know.

Of course Jenner's children wasted no time paying tribute to her, with Kim Kardashian leading the Instagram posts dedicated to her.

She penned alongside a series of snaps with her mom over the years: "HAPPY 70TH BIRTHDAY TO THE MOST BEAUTIFUL WOMAN ON THE PLANET! There is no one more special in this whole world than you! You are so blessed with the most amazing family surrounded by so much love!

"You truly are super woman and have been the absolute best role model just in the way you lead and live your life with such grace and compassion and joy! I Wannabe just like you when I grow up and have always said this my whole life! I love you so much mom!"

In a separate lengthy post to her mom, Khloé Kardashian gushed: "Mommy, seventy years of pure magic, grace, laughter, and best of all, love. Somehow, you just keep getting more radiant. More fabulous by the day.

"You are the heartbeat of our family, the light that guides us all, the one who created this beautiful, wild, loving universe that we call home. That is your superpower, your love; limitless, unconditional, eternal."

She went on to describe her mother as '[her] greatest inspiration' and ' the woman who made magic out of motherhood'.
