The New York Post is reporting that Britney's all night partying with her new crew, Paris Hilton, Nicole Richie, Brandon Davis, and Lindsay Lohan has caught the eye of the Los Angeles Department of Children & Family Services:

A source close to the singer said, 'The department has been calling Britney trying to set up a meeting with her, so they can check on [Spears' baby sons Sean Preston and Jaden James]. The calls started after this recent bout of bizarre public behavior.'

Kevin Federline and his lawyer have got to be loving this one! But it gets better, Britney's family is concerned about her recent behavior:

Her family is aghast at her all-night partying with Hilton and Davis and were mortified when, on four separate occasions, Spears was shot by paparazzi not wearing any underwear.The family source said her mother, Lynne, 'is very disturbed and has been trying to get a hold of Britney, but she can't. Lynne, Britney's brother, Brian, and her dad, Jamie, are very upset and are trying to stage an intervention with [Spears' manager] Larry Rudolph's help.'

This wouldn't be the first time Britney has faced public scrutiny for her parenting skills. On April 8th the LA County Sherrifs Department was called to her Malibu home after Sean Preston fell from his high chair and hit his head while under the care of a nanny. On May 18th, a pregnant Britney was pictured almost dropping baby Sean Preston when she slipped in her open-toe wedge shoes and then there is the famous picture of Britney driving her car with Sean Preston un-restrained sitting on her lap from February.
