Britney’s parenting skills are again criticized by a source close to the court appointed parenting coach the star is working with. According to the Us magazine, the unnamed parenting source has given a “very damning” repot that could harm the singer in her ongoing custody battle with ex-husband Kevin Federline.

The court has ordered Britney to attend parenting classes and undergo regular drug tests in order to claim the custody of the kids. Scott Gordon, the judge presiding in the case previously called Spears a “habitual, frequent and continuous” user of controlled substances and alcohol and laid down several conditions for Britney in order to regain 50-50 custody of her sons.

According to an insider the documents filed by the parenting adviser say that the Toxic star was distracted and argumentative during the sessions. A source said “Britney’s often distracted and in her own world when she has the kids and has a hard time focusing. She is adamant that she doesn’t have to listen to anybody- that it’s her way or the highway.”

The insider tells that the initial guidance sessions were held at Spears’ place but now the parenting coach has asked for meetings to be organized in offices to keep the paparazzi away. The magazine was also informed that Spears was not cooperating with her parenting coach and paying her “no attention or respect to all.”
