Kris' boyfriend, Corey Gamble, sat right next to the birthday gal, smiling and joining the star-studded group as they sang "Happy Birthday" to Kris and pal Simon Huck, who was also celebrating his special day.
"Double birthday dinner last night @simon_huck @krisjenner," Jonathan Cheban later wrote on Instagram, accompanied with a group photo.
He also shared a selfie with Kris, which he captioned, "Happy Birthday to the kindest most generous person I know! Love you for always being there for everyone you love! Ohh..and looking more beautiful every year! #family."
While Kris was partying with friends, Khloe Kardashian was at home babysitting sister Kourtney's three kids, Mason, 6, Penelope, 4, and Reign, 1, whom she shares with Scott Disick. On Saturday, she was the first of her siblings to wish her mom a happy birthday via social media.
"Happy birthday mama!! My greatest wish is to grow up and be as fantastic as a mother as you have been to us!" she captioned a sweet family photo from last year's Gatsby-themed soiree. "Thank you for always being there for every single one of us! You are our angel! I love you mommy!"
Meanwhile, Rob Kardashian and his pregnant fiancée, Blac Chyna, delivered massive balloons to Kris' home, which spelled out, "Happy Birthday" and "Love You."
"Thank you Rob and Angela for the amazing Birthday Balloons!!!!!!" Kris wrote on Instagram. "So so sweet I love you guys!!!!!@robkardashian @blacchyna #blessed."
Kim Kardashian didn't post anything on social media, as she's been silent following her traumatic robbery in Paris, France, last month, with the exception of a Facebook post that has since been deleted. She did, however, give her mom a pretty epic gift.
"Thank you Kimberly for making me my Birthday Kimoji!!!" Kris wrote, sharing a screenshot of the Kimoji which shows her holding a "Queen of F**king Everything" phone case. "I love you so much my beauty @kimkardashian #kimoji #priceless."
