Carrie Underwood, Steven Tyler's 'Super Bowl Fan Jam'
"I'm excited about our opening. I don't want to give away too much," Carrie tells CMT.
"And I'm excited about a marriage of two songs that we put together, which is phenomenal," says Tyler.
Tyler adds that the surprises in working together came from Tyler see that Carrie "has a real hard side, and she got to see my soft side."
"I knew that was there! You're a sweet guy," Carrie adds.
"Her band and her voice are so beautiful. And these country players - forget about it," Tyler adds. "They're good. We're so good."
"They're good. He's good," says Carrie.
Well, we can't wait to see it.
