The New York Post is reporting that Britney Spears's recent partying has caught the attention of the LA Department of Children and Family Services. An insider told the paper, "The department has been calling Britney trying to set up a meeting with her, so they can check on [Sean Preston and Jayden James]. The calls started after this recent bout of bizarre public behavior." The source also says Britney's family are equally concerned, especially with last week's very public and very intimate candid shots of the popstar seen all over the internet. Britney's mom, Lynne, "is very disturbed and has been trying to get a hold of Britney, but she can't," says the insider. "Lynne, Britney's brother, Brian, and her dad, Jamie, are very upset and are trying to stage an intervention with [manager] Larry Rudolph's help." A rep for Children and Family Services in LA did not return calls. US mag is also reporting that Britney's father is concerned. "He was not happy with her antics..." a source said. "He told her that she's a grown woman and needs to act like one, and she's been making bad decisions."
