Drake just dissed Kid Cudi by making fun of his life-threatening depression … and people are pissed.
Drizzy dropped new music on the eve of his 30th birthday, and one of the songs — “Two Birds, One Stone” — clearly calls out Cudi as an angry guy who takes drugs to deal with reality.
You’ll recall … Cudi called out Drake and Kanye last month for refusing to work with him. He checked into rehab a few weeks later for depression.
Apparently turning 30 brings out Drake’s worst behavior.
