Kanye West has dominated the news cycle over the last few days with his still unreleased album The Life Of Pablo.

The rollout has been brilliant or bi-polar or maybe a bit of both.

In other words, it's been classic 'Ye.

However, his old buddy Rhymefest -- who came up with West in Chicago, and who's written for him credited or otherwise -- sees something especially disturbing in 'Ye's recent behavior.

He explained his concern on Twitter.

While Rhymefest isn't a mental health professional, he has history of offering mental health diagnoses: Last year he informed the world that Chief Keef was autistic, citing Sosa's facial structure.
