Jackson questions Spears as mother

Shar Jackson has expressed doubt that the pregnant Britney Spears realises what motherhood entails.

Jackson, who has had two children by the singer's husband Kevin Federline, feels that he is not ready to become a father for the third time. She explained to Touch Weekly: "He has told me it is really a lot, what with a breakup, a wedding and two babies in a year."

Even if Federline is to father another child, Jackson is adamant that the Crazy singer should not be the mother.

She noted: "A baby is not a dog, you can't just put it away. I don't know if Britney realises how hard it will be."
