Mariah Carey

Pop/R&B star Mariah Carey is looking out for her best financial interest in the wake of her successful album ?The Emancipation of Mimi.

According to Fox411.com?s Roger Freidman, the singer has hired record business attorney Allen Grubman to help her take care of business in the Island/Def Jam conference room when it?s time to update her pact with parent company, Universal Music Group.

Friedman writes: ?Carey, I?m told, feels that she was underpaid by Island/Def Jam for her "Emancipation of Mimi" album. ? Passman, sources say, while good, does not have the inside track Grubman has with Universal Music Group?s Doug Morris. Only Morris can OK what should be a record-setting money deal for Carey. And only Grubman can get Morris to agree to something like that.?
