Carey, who recently announced that she will be touring with Lionel Richie starting next year, got the biggest stamp of approval at her "All I Want for Christmas Is You" two-week stint in New York from none other than fellow pop icon Bey, who visited the star backstage alongside big fan and daughter, Blue Ivy Carter.
"Backstage at Christmas time with our beautiful children," the "Endless Love" hitmaker captioned a 'gram on Monday, which shows the two starlets posing in the background while their adorable toddlers, dressed head-to-toe in festive gear for the holiday show, smile for the camera.
Carey's 5-year-old twins are officially too cute, with Moroccan donning a bright red sweater while Monroe added some pizzazz to her red coat with a checkered newsboy cap and matching red glasses, but we can't tear our eyes away from 4-year-old Blue Ivy, who proved she's definitely Beyoncé's mini-me with one fabulous move.
The "Formation" singer's only daughter amped things up in the accessories department with a large bright red fan, which she dramatically held in front of her mouth for the holiday close-up.
