Wow! You can see that Miley Cyrus HATES competition, especially when it is a hotter girl and one that everyone is stating will replace her. But wait we also hear now that not only is she replacing her she is now with Miley's ex. Oops. Yep, it's Selena Gomez. Miley Cyrus recently with the help of her friend Mandy, attacked Selena and Demi's show that they do on Youtube. You can really see her age showing now can't you? I almost forgot she was a teen.
