Diamond Brown wants a look at Chris Brown's books — and she says his people have been stalling her for months.

The mother of the singer's daughter Lovely says in new court filings that she hit a wall after she subpoenaed his business managers for records showing what he really earns. They objected, leaving the two sides deadlocked over what has to be turned over.

Diamond argues she cannot pin down his actual income without those documents. In her view the paperwork is the only way to know what he brings in plus what he can truly afford to pay.

The numbers

Her filing puts Chris' net worth at roughly $50 million. She says he currently sends her about $7,000 a month for their little girl.

Diamond claims she has only $10,000 to her name. She wants his monthly payments raised to no less than $30,000.

Other moms take his side

This is not the first time her support case has grabbed headlines. After her earlier filing the mothers of Chris' other children went public to defend him, insisting he is a good father who looks after all of his kids.
