Britney's father reveals stress of recent court battle

Britney Spears' mother struggled with their recent court battle more than the popstar.

The 30-year-old 'X Factor' USA judge's father Jamie Spears has opened up about the family's recent victory against her former associate Sam Lutfi - whose defamation, battery and breach of contact case against the family was thrown out on Thursday - and said Lynne Spears found reliving their daughter's darkest days extremely painful.
