Cheyne Thomas, better known as "Miley Cyrus' BFF," has allegedly made fun of Demi Lovato's stuggle with cocaine.


Demi recently admittled that at one point, she couldn't go much longer than 30 minutes without a cocaine fix. Thomas made a video that mocked her confession.


Cheyne was also the one who recently fat-shamed Kelly Clarkson in "defense" of Miley.
