The pair looked stunning as they wore matching white gowns and tiaras on their head. They were surrounded by Christmas trees and other decorations for the cheerful holiday as thousands of audience members cheered them on–cheering extra loud for Monroe as she shined next to her grammy award-winning mother.The fan behind the camera was in shock, yelling an occasional “What?!” and “Yes!” as Monroe started to sing. Carey shares Monroe and her twin brother, Moroccan, with Nick Cannon.This isn’t the first time Carey’s daughter has joined her mom on stage. Back in 2017, the then 6-year-old and her brother frequently joined their mother on stage during the songbird supreme’s “#1 to Infinity” Las Vegas residency for a special live performance of her 1995 hit “Always Be My Baby.”  The twins also joined their mother on stage as she closed out the Macy’s Thanksgiving Day Parade last month! The two could be seen dancing behind Carey on stage as she performed her No. 1 hit, “All I Want For Christmas Is You.” For those of you who wished they could have experienced Carey’s Christmas show, the singer will be streaming her special, Mariah Carey: Merry Christmas to All on Paramount+ and will air on CBS on Dec. 20, at 8 p.m. ET/PT.
