At long last Selena has achieved her dream of singing a duo with Katy Perry.
On Selena's newest CD A Year Without Rain, you'll hear 'Rock God' which she sings with Katy in the chorus.
Katy gave Selena this song and Selena adapted it to fit her voice and style. She gave it a bit more of a techno feel.
Selena is really happy about this collaboration and how the whole thing turned out. Selena really admires the"California Gurls", singer, and may even dress up as Katy for Halloween.
