Mariah Carey, the queen of Christmas, has two ridiculously cute kids on her hands. On Friday, the singer posted a video of her twins joining her on stage during her holiday concert at the Beacon Theatre in NYC. In the clip, Mariah asks Moroccan to give her a kiss, but the cutest part might be when little Monroe strikes a pose like her famous mom. Moments later, Monroe introduces herself to the audience, saying, "Hi, my name is Roe Roe," and naturally, everyone melts in their seats.
