While it's unclear exactly why they could be fighting, they were on shaky ground already, when Miley's friend Cheyne made fun of Demi's addiction confession last year. So not cool. Did something else go on behind the scenes we don't know about? Because there was some shade throwin' going down.
So, this is what went down. Demi unfollowed Cheyne, Miley unfollowed Demi, then Demi returned the unfollow. Then she tweeted "Ain't nobody got time fo dat!!! #pettybullshit #toobusykillingit #cutethough #NEONLIGHTSTOUR
Um...what's "dat" that she ain't got time for?
