Live from ABC News headquarters in New York City. This is Good Morning America. And good morning America. It's great to have you with us. Nice words of wisdom from Shaq on this Sunday morning, right? Yes, it's very wise. Yes, yes. In Rihanna, it's great to have you at the desk. Gio is off this morning.

Very happy fans.
