Beyoncé had a monumental night at the Grammys on Sunday, but it was really her 5-year-old daughter, Blue Ivy Carter, who ended up stealing the show [1]. Not only did she crash James Corden's star-studded Carpool Karaoke session [2], but she appeared to be having a blast [3] cheering on her famous mom with dad Jay Z and a friend in the audience. But who exactly was her adorable pal, you ask? Well, as it turns out, the little girl is Madison Brown [4], the daughter of Roc Nation president Jay Brown (Jay Z founded Roc Nation in 2008). Jay is Jay Z's longtime friend and business partner and also happens to be Rihanna [5]'s manager. So there you have it.
