Kris Jenner turned 60 on Thursday, and her kids are making sure this major milestone is celebrated accordingly.

On Friday night, there will be a "Great Gatsby"-themed party in honor of the momager, and it is being thrown by all six of her kids: Kourtney, Kim, Khloé, Kendall, Kylie and even Rob, according to Us Weekly. Her children are throwing the party "because we love her," according to the sleek black-and-white invitation which says that the most likely over-the-top party will take place at a venue in West Hollywood and there will be "champagne flowing, dinner and dancing."  

Apparently, the stars of "Keeping Up With The Kardashians" have rented out a giant soundstage which will be filled with about 300 people, according to TMZ. Each of her famous kids chipped in and it is costing them more than $2 million. There will also be some huge stars performing, but it is unclear exactly who.

With Kim's husband being Kanye West, Kylie's boyfriend being Tyga and them all having too many famous friends to count, we can only imagine how spectacular this event is going to be. All of the siblings took to social media on Thursday to wish their mom the happiest of birthdays and to thank her for all she has done over the years.

"Happy 60th Birthday to my best friend & mom," Kim captioned a black-and-white selfie of the two. "Now that I'm a mom I have realized how hard your job is & no one does it better than you. I love you so much!"

"Happy 60th Birthday to the baddest bo$iest momager alive!" Kourtney captioned another selfie. "You have taught me how to celebrate life, make memories and live in the moment and I cherish everything I learn from you every day."

"To the real OG! Happy birthday boss!!!" Khloé captioned a photo collage. "Throughout my life, you have always been the strength that holds me up in the storm of life. I love you my gorgeous Mama."

"The moment we met," Kylie captioned a framed photo from the day she was born. "Happy birthday mommy."

"Mama I love you!!" Rob captioned a paparazzi shot of the two out to eat together. "P.O.P. Holding it down...Happy birthday to my beautiful mama!!!"

Kendall decided to wish Kris a happy birthday on her website by celebrating with her top 10 outfits of all time. "Happy birthday to the best mom ever!" she wrote.
