So Cute: Beyoncé & Mariah Carey Pose with Their Adorable Children [Photo]

Beyoncé attended Mariah Carey’s Christmas show at the Beacon Theater in NYC on Sunday night.

While backstage, Mariah and Bey posed with their kids – Moroccan Scott, Monroe and Blue Ivy.

We’re not entirely sure who that other little girl is — but she’s adorable in her little bow headband!
