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.

The NSFW photo is not really that raunchy -- it's not like Miley removed her top or grabbed stripper bootay in this one -- but it is certainly all grown up. Her tweet indicates that someone -- maybe fiancé Liam Hemsworth or one of her close girlfriends? -- gave her the doll as a gag gift. She has a sense of humor about the whole thing, though. We'd love to see Cyrus pull up to a McDonald's drive-thru with her "friend" alongside her. Could you imagine the employee's face upon seeing that strapped in the front seat?

Cyrus posted the following caption:

Does this count for the carpool lane? Such a nice Xmas gift.

We have to say that we love the fact that Miley doesn't take herself too seriously. She's started to come under fire in the press about some of her actions as she's graduated from Hannah Montanadom. This photo shows she DGAF. You know what that means, right? Figure it out!
