It looks like another chapter in Demi Lovato and Miley Cyrus' on-and-off friendship could be unfolding.
The two former Disney stars are no longer following each other on Twitter, pointing to signs that they may be butting heads yet again. Celebuzz.com says the rumored rift could stem from a tweet Demi sent out earlier this month, joking that the words "twerk" and "turnt" -- two words commonly found on Miley's page -- "need to disappear."
But their "unfollows" could stem from a more serious comment from back in December, when Miley's friend and personal assistant Cheyne Thomas posted a video that seemed to poke fun at Demi's 2010 stint in rehab.
Demi may have been responding to questions from fans when she posted a photo of a crowded arena on her "Neon Lights" tour, with the caption "Ain't nobody got time fo' dat!!!"
