Mariah Carey is keeping this one close to the chest.
Isn't Monroe totally ADORBz? She looks like a baby rockstar in those tiny shades!
Hmm, baby rockstar… We have a great idea for a new energy drink… LOLz!
Srsly though, we still don't know what Mariah was doing in NYC! Filming, producing, just hanging with friends?
The only thing we know she was doing is being an awesome mom!
