Britney Spears in 2019 Britney Spears ’ team has responded to allegations made about the singer by her ex-husband Kevin Federline . The Piece Of Me singer and former back-up dancer were married for three years between 2004 and 2007, during which time they had two sons, Sean Preston and Jayden James. Earlier this week, the New York Times published an excerpt from Kevin’s upcoming memoir You Thought You Knew which contained allegations about the Grammy winner. In his book, Kevin claims that the former couple’s sons would express fear to him at the prospect of staying at Britney’s house, alleging: “They would awaken sometimes at night to find her standing silently in the doorway, watching them sleep – ’Oh, you’re awake? – with a knife in her hand. Then she’d turn around and pad off without explanation.” A spokesperson for Britney has since issued a statement to Metro , accusing Kevin of “sensationalism” and pointing out that the release of his memoir comes shortly after she was no longer required to pay him child support, as both of their children are now over the age of 18. “With news from Kevin’s book breaking, once again he and others are profiting off her and sadly it comes after child support has ended with Kevin,” the statement read. “All she cares about are her kids, Sean Preston and Jayden James and their well-being during this sensationalism. She detailed her journey in her memoir.” Britney and Kevin legally tied the knot in October 2004, six months after meeting. Two years into their marriage, the pop singer filed for divorce, citing irreconcilable differences, and the pair initially agreed to share joint custody of their sons when their marriage was finally legally terminated the following year. Kevin was later granted sole custody of their two sons, shortly before Britney was placed under the temporary conservatorship of her father, an arrangement which remained in place for over a decade until it was dissolved in 2021 .
