Mariah Carey and Daughter Monroe Sing in First Christmas Duet Performance

Mariah Carey and her 11-year-old daughter, Monroe, perform their first duet at Mariah’s Christmas concert in Toronto, Canada. While it's the first time the pair has performed together, singing holiday hymn 'Away in a Manger,' it's not the first time Monroe's joined her mom on stage. Most recently, she and twin brother Moroccan, danced alongside Mariah during her Macy's Thanksgiving Day Parade performance.
