Miley Cyrus trade in her Porsche Cayenne for the eco-friendly Prius

So just what made Miley Cyrus trade in her Porsche Cayenne for the eco-friendly Prius? According to teenhollywood.com, Miley told Ryan Seacrest that she wanted to practice what she preached to her fans! She said, "I'm really into the environment; I'm always telling people to get more into it and there are different ways to stay green and then I'm driving, like, this big ol' tank and I'm like, 'That could not be any more hypocritical.'" Cyrus apparently sold the Porsche to a family friend but only after she convinced her Dad that it was ok to buy a chick car (the Prius.)
