2 Chainz was the guest on BET's 106 & Park, and he was there to talk about his new music, what fashion he's into, Nicki Minaj, and that new "Mercy" joint. What the crowd didn't expect to see was Kanye West. Kanye stepped in the building to show some support, but didn't say a word. Nobody seemed to mind though; his presence was like a giant stamp of approval, and that was enough.
