There was nothing on TV for me at 8pm so I watched the CMA's for an hour. To my surprise while Carrie Underwood was singing out comes Steven Tyler all in white with his long coat and he sang with her. Then they both sang Walk This Way, the audience went wild. I was surprised to see Steven since he is in no way, shape or form a Country singer but he was there and rocked the house. I'm glad I caught that.
