Britney Spears is preparing to move for full custody of her two sons with former husband Kevin Federline, The National Enquirer claims in its Oct. 19 issue.

The “Toxic” star is considering filing a motion to restore her rights as primary guardian of sons Sean Preston, 4, and Jayden James, 3, once her conservatorship with father Jamie Spears ends in November.

“She is ready to fight to get her boys back. Britney feels that leaving Kevin in charge has turned her sons into cursing, ill-mannered little boys who don’t behave. Britney wants to be the one who chooses where the boys go to school and where they go to church,” a spy spilled to The Enquirer.

Tipsters say Britney is concerned about the way her sons are being raised by Federline — who was accused this week of property damage and failing to keep up with rent payments on his Tarzana home.

“She wants full custody and for Kevin to have visitation. Britney feels that Kevin is now the one with problems that the judge needs to hear about. She believes he’s become a poor role model for Sean and Jayden,” the insider added. “The boys are used to Kevin’s foul-mouthed, lazy, unemployed dancer friends, who either live at the house or hang out there. Britney doesn’t want the boys growing up thinking that kind of lifestyle is acceptable.”
