RUSSELL TO FEEL THE POCKET PAIN

Sounds like Rush is about to feel the pain of separation in his pockets.



TMZ has obtained documents in the Russell and Kimora Lee Simmons divorce case filed yesterday in LA Superior Court reporting that the hip-hip pioneer has to shell out $20k a month -- per daughter!!! -- in child support to Kimora.

And he's got to keep doing so until 2019 for Ming Lee and 2022 for Aoki.

GV Says: I'm not mad. It is what it is.
