It's called the Child Custody Evaluation report. Sources say it is "several hundred" pages long, and lawyers for both sides received it on Friday. Our sources say the report is a "mixed bag" -- both encouraging and damaging for Britney.
The report, written by Dr. Jane Shatz, is extremely detailed. There is a hearing next week (May 6) in the custody case and the report could be all-telling.
And, sources say, the report "makes it more likely that Britney will show for the hearing."
Lawyers for both sides refused to comment or respond.
