Mama June -- 'My Mom is a Money Hungry Bitch' (VIDEO)

Mama June is angry and clear ... her own mother has driven a wedge between her and Chickadee, because she's "a money hungry bitch."

June flew into LA Wednesday and told our photog, it's Chickadee's own fault she's run out of cash ... June says she's given her plenty.

June then made it clear ... the gravy train has left the station, so Chickadee needs to fend for herself.
