According to TMZ, in 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.
