Disney is probably regretting that it was ever in the Miley Cyrus business. The singer and actress, who has shed any semblance of a goody-two-shoes image since she lobbed off her hair and began hanging with porn stars and strippers, loves showing off her good-girl-gone-bad side. She tweeted a photo while in the driver's seat of her car. That's pretty innocuous, right? Not really, when you consider who her passenger was. Who was riding shotgun? Why a blow-up doll of herself, that's who.
