OH MY GOD.
This is infinitely better than her Good Morning American performance of this song. Strangely, she was a bit out tune in places, which is something I'd never expect from Whitney, but wow, I hope her voice just continues to get better. This performance and her one on Oprah (Didn't Know My Own Strength), are the best she's done in well over 5 years.
However, I didn't like her interview at the end. Seemed a bit fake.
