The parenting coach assigned to Britney Spears has reportedly submitted a “very damaging” report to the court overseeing Britney’s custody case.

The coach spent two afternoons a week with the star for the last month ahead of this Friday’s hearing at the Los Angeles Superior Court and according to leaked comments, the report concludes that Britney often ignores the children and frequently disappears into her own world, either physically or mentally, when she should be caring for them.

A source told Us Weekly: “Britney’s often distracted and in her own world when she has the kids and has a hard time focusing.”

According to the source, the report also notes how the Gimme More singer “paid [the coach] no attention or respect at all, as if she were some employee whom she could blow off.”

“She is adamant that she doesn’t have to listen to anybody.”

Britney lost custody of two year old Sean and one year old Jayden at the start of month after Court Commissioner Scott Gordon expressed concern for her “frequent and habitual” drug use. She then lost her visitation rights last week after failing to comply with the court’s criteria but has had two monitored visits with the boys since the sessions were reinstated last Friday.

Ex-husband Kevin Federline started his challenge for a 70/30 custody split in the summer when they were sharing the children equally but is now expected to request full permanent custody.
