Britney Spears overwhelmed by motherhood

"I'm so nervous I'm not doing things right," Britney reportedly told a friend. Her rep insists that she's fine.

A licensed therapist cited by the magazine that does not treat the pop princess says that this type of obsession and quick irritability are two signs of postpartum depression reports National Ledger.

Meanwhile, Britney is said to be upset that Kevin is not spending enough time helping her with their baby son, Sean Preston.

Insiders claims she was particularly annoyed when her husband spent two hours having his hair braided, while she was left to change the baby's diapers.

Kevin, who has two children with ex-girlfriend Shar Jackson, has also reportedly been avoiding his fatherly duties by partying till the early hours at nightclubs.
