The family was in awe of Carey, Monroe and their talents as they took in the performance
The SKIMS founder, 43, and the Good American co-founder, 39, got to take daughters Chicago and True, both 5½, along with Dream, 7, North, 10, and the momager, 68, to see Mariah Carey's Merry Christmas One And All! show at the Hollywood Bowl.
Not only did they get to enjoy the show together, but they also got to meet the Queen of Christmas and her own daughter, 12-year-old Monroe, and pose for some photos afterward.
"The Queen of Christmas!!!! For the little girls very FIRST concert ever, we went to see the Queen herself, @mariahcarey !! We all had the best time, creating the most magical memories!! Thank you mommy for taking all of us! ," Khloé captioned photos from the night.

In an earlier post, Kim filmed the "All I Want for Christmas Is You" singer on stage. "Legendary!!! @mariahcarey," the reality star wrote over the video.
Next, she filmed a selfie video in which Chicago appeared to be asleep during the show. The little one had a pair of sunglasses on as she rested in her mom's arms.
"LOL" was written across the clip, which also showed North and a friend having fun in the background as the festive track "Sleigh Ride" was heard.
Other posts on her Instagram Story included a video of Carey's daughter playing guitar on stage.
"Go Monroe," Kim captioned the post.
The singer just recently announced the launch of her very own Barbie, which retails for $75 and even wears a glamorous sparkling red gown befitting of the legendary star.
"If I could go back and tell my little-girl self that one day I would have a Barbie made in my likeness, I would flip out!" Carey told PEOPLE of the feat earlier this week.
