Britney Spears and hubby Kevin Federline are encountering problems in their marital life.

Recently, the superstar wife hurtfully laughed at her husband who played her a piece of music that he had recorded.
The new parents are going through a rough patch and her tolerance for her hubby's casual behavior is depleting.
Kevin was busy getting himself braided when Britney was changing baby son's diapers. And after a feud between the duo, Federline went to a nightclub called Mood and partied well beyond midnight.
