Lynne Spears sticks up for son-in-law

Britney Spear’s mum Lynne is reportedly set to back ex son-in-law Kevin Federline instead of her own daughter in their custody battle.

Lynne, 52, is backing KFed to take sons Sean Preston, 23 months, and 11-month-old Jayden James, from out-of-control Britney.

Kevin is so fed up of her crazy behaviour he’s filed court papers demanding ‘primary custody’ of the kids.

According to the Daily Star, Lynne is even ready to take the stand and give evidence against her daughter.

Britney, 25, and Lynne have been arguing for the last year about Britney’s increasingly erratic behaviour.

The glamorous gran admits she is close to Kevin, but has not commented on the feud with her daughter.
