Forget Chris Brown and Drake, or Chris Brown and Frank Ocean, or Rick Ross and most gangs; there’s a new rivalry in the rap world. Jay-Z’s got beef with a 2-year-old.

Like, he knows the whole starting lineup, he can say their numbers, he can say their names and at night, he has a special song for Melo [Carmelo Anthony] that he sings. And J.R. Smith. It's very cute."
