The Edge: Kevin Federline’s latest move to make money off Britney Spears

CHARLOTTE, N.C. – Britney Spears is hitting back at her ex-husband, Kevin Federline. In Federline’s new memoir, he accuses his ex-wife of some shocking behavior toward their two sons, including watching them sleep while holding a knife in her hand. On Wednesday, the pop star called his “constant gaslighting about her parenting…extremely hurtful and exhausting.” The two got married in 2004 and divorced in 2007. A spokesperson for Spears accuses Federline and others of continuing to profit off her.
