Graceful is as graceful ... does not. Accident-prone Miley Cyrus apparently busted her tailbone while attempting to channel Nadia Comaneci in her living room the other day. "Cracked my tail bone doing a front flip... on to the couch. thats like when i tripped over a pillow and broke my arm. #onlyme," she tweeted this week.Whatever she still looks cute. :)
