Christina Milian Taking Dream Back To Court Wants More Money off Bieber Songs

This is what happens when a man marries a jump off/gold digger and then cheats on her.  That's right Christina Milian is "going in" and wants it ALL. Christina is trying to drip this sucker dry!! and we think she should.  

The Dream and Christina Milian are battling each other over their divorce settlement -- and the wrench in the works is apparently none other than Justin Bieber ... TMZ has learned.

According to docs filed in Georgia, The Dream previously agreed to pay Milian a hefty settlement -- including 10% of his publishing interest in Bieber's mega hit, "Baby," which The Dream co-wrote.

The Dream is pissed because Milian is trying to re-negotiate the settlement by demanding more support, including a greater percentage of the Bieber gold mine.  Since Christina tried to renegotiate ... The Dream is trying to pull the plug on any payments to her. Obviously, Christina is fighting that.
