R&B singer, songwriter and producer The Dream and his wife Christina Milian are reportedly fighting over Justib Bieber, if you can believe it.  The Dream, real name Terius Youngdell Nash, claims he and Milian previously agreed on a divorce settlement that would pay her a hefty sum in cash plus a ten percent stake of his publishing interest in Justin Bieber's mega-hit, "Baby," which he co-wrote.  Milian, Nash says, now wants to renogotiate the agreement, including a bigger stake in the Bieber tune.  Because Milian's attorneys tried to get more money, The Dream's attorneys have pulled the settlement offer off the table completely.
