Remember 2009, when a young Miley Cyrus brought a slightly younger Demi Lovato to the U.K. premiere of the Hannah Montana movie because they were best friends?

Like, BFFAEAE?

Those days are gone.

Demi announced once and for all during a radio interview this morning that she and Miles are no longer BFFs. They are no longer even Fs. Per Demi:

Um...we're, we're like, we're acquaintances. It's life, and people change, and, you know, I don't have anything in common with her anymore, and I wish her all the best.

It's rumored that once Demi started living a sober lifestyle last year after suffering from an eating disorder, the pair drifted apart.

Miley's new best friend rode a giant penis with her at her birthday party this weekend.
