Miley Cyrus recently confessed that she is obsessed... with cleaning.
Miley tweeted that if she could change one thing about herself it would be to eliminate her cleaning OCD:
if i could change one thing about myself it would be my ocd. why do i never stop cleaning?! drives me nuts!
Obsessive Compulsive Disorder can cause people to become obsessed with doing certain things such as making sure a door is locked or washing hands.
I'm guessing Miley has a mild form of OCD which causes her to have anxiety if something is not neat and clean.
