While you're muddling over that alleged Miley Cyrus photo, consider this: the person who leaked that photo to 4chan also leaked the following alleged photos. Do they seem more or less legit than the Miley photo? Take a look.

Ali Larter, or another woman's boob? (Her wedding ring, for comparison)
Dee Dozier, or definitely not?
