Katy Perry will be doing a duet with Stevie Nicks, like it or not. Nicks was quoted saying: I’m going to do a song with her someday. She doesn’t know it, but I’m going to, because I really do like her. I love the song E.T. I feel that sadness of almost like the E.T. movie and I love it. So I think she’s really good.” Sorry to say Stevie, but even trying to piggy back on Katy’s success isn’t going to put you into that demographic of listener!
