I mean, of course she does.
Of course Miley Cyrus has a skate ramp behind her house. I imagine that was the first thing she did when she bought her post-Hannah Montana house: looked over the backyard and announced, "This looks good, but tear up those begonias and put in a skate ramp."
And then everything went hazy and the next thing she knew she had blonde Zack Morris hair and a fistful of Molly in one hand and a teddy bear in the other.
The singer explained to Harper's Bazaar that she had the skate ramp put in because she's too famous to go to the skate parks in her neighborhood. No word on where or when she learned to skate — Cyrus also mentions that "Hannah Montana" made her childhood so busy that she was basically a vampire. "I had to have [the producers] put sun lamps inside because I was getting depressed from a lack of vitamin D," she said.
Cripes. OK, she's earned a little twerking. She basically spent her childhood as a Dickensian orphan.
