Spears 'competing for sons' affection'

Britney Spears reportedly feels like she is competing for the affections of her sons with Kevin Federline's new girlfriend Victoria Prince.

Pictures of her boyfriend's new partner holding her children were recently published in Life&Style magazine.

An insider told the publication that the singer would be distraught at the sight of the images.

"Her kids are her life. Seeing someone else caring for them like this - holding them, comforting them - will absolutely devastate her," said the source.

Federline's ex-girlfriend Shar Jackson recently said that she is "proud" of Spears and wishes her success in the future.
