This is Mariah Carey's daughter, Monroe.
She goes by "Miss Monroe," and she's a diva-in-training, according to Mimi.
Well, Monday night at the Hollywood Bowl, Mariah brought her kids onstage.
And after a little encouragement, Miss Monroe started singing the chorus of "Always Be My Baby."
At one point, both of them were just belting out the number one hit.
Ugh, so cute.
Like mother, like daughter.
You can watch the festive moment here!
