Party girl Miley Cyrus may be trying to clean up her ways…at least in the day time. She’s been papped every day heading to and from the gym and now all the sudden she’s got that tiny pilates body with her hip bones sticking out.

We forget that the worldy Miley is only 19, so this might just be the time of her life when she loses her baby fat. Or maybe she’s laying off the weed and midnight munchies and getting healthy.
