LATEST: Britney Spears' parenting coach testified at Friday's (26Oct07) hearing, a newly released court document has revealed. The document shows that parenting worker Lisa Hacker was sworn in and testified in person, and her report was also submitted into evidence. The contributions could prove critical in determining whether the Toxic singer is fit to be a mother. The star's attorney Sorrell Trope says of the report, "There were some negative things, and some positive, but the beneficial things far outweighed the negative." The document also shows that just hours before the hearing (25/26Oct), Spears's attorneys filed two last-minute requests to the court seeking "modification to drug testing," but no details were given. The singer is currently undergoing regular co-parenting counselling and classes with ex-husband Kevin Federline, and is also subjected to twice-weekly random tests for drugs and alcohol. The commissioner's complete ruling is expected later on Tuesday (30Oct07), and the pair's next hearing is scheduled for next month (26Nov07). Currently, Federline retains physical custody of their children, Preston, two, and Jayden James, one, while Spears has monitored visitation rights.
