Taylor Swift and the Rolling Stones Duet Partners

Taylor Swift and the Rolling Stones? Not exactly the first duet idea you'd come up with but last night in Chicago they performed "As Tears Go By" together. Our cameras were there to bring you the duet with the "Lips" and the "Hips".

And, as I asked Chad, I ask you. How does she get back stage in Chicago or any other place? Does she had a lifetime, anywhere backstage pass? Or, does she show up and "Hi, I'm here, let me back stage"?

And, dressed like that? Surely she had a dressing room to doll up and put that rubber band on.

Did any other Stones say, "What"? "Who"? "Why"?
