Britney Spears' beef with her father was intensified after she lost a percentage of custody after Jamie Spears got into it with her son Sean.
According to Us Weekly, the pop star blames her dad for having less time with her two kids, 14-year-old Jayden and 15-year-old Sean Preston.
Britney's ex-husband Kevin Federline has the majority of custody of their teenagers and has had for some time. A source close to Britney denies her father's claim they were on good terms in August.
