Okay, What the Fuck Is Tyra Talking About?

Earlier this evening Tyra Banks tweeted out, "U know how they have muffins where u can only have the tops? They need 2 figure out how 2 do that w/pizza. I just like pizza tops!" which leads us to ask: what on Earth is Tyra talking about?" Cheese? Is "pizza tops" what Tyra Banks calls cheese?

Please speculate.
