After years of public scrutiny, Britney Spears is once again facing allegations from her ex-husband, Kevin Federline — this time through the pages of his upcoming memoir You Thought You Knew.
The former backup dancer’s book, set to be released on October 21, includes shocking claims about the pop star’s behavior during their marriage and parenting years — but Spears and her team aren’t staying silent.
Britney’s Representative Accuses Federline of “Profiting” off Her Life
In a statement obtained by The Daily Mail, a representative for Spears called out Federline for allegedly using her name for financial gain — especially now that his child support payments have ended.
“Once again, he and others are profiting off her,” the rep said, adding that Spears’s only concern is the well-being of her sons, Sean Preston, 19, and Jayden James, 18.
“All she cares about are her kids and their peace amid this new wave of sensationalism.”
Spears Reportedly Unbothered by the Memoir’s Claims
According to a source close to Spears, the singer isn’t losing sleep over what’s written in the book.
After sharing her own story in her 2023 best-selling memoir The Woman in Me, she reportedly feels she has nothing left to prove.
“Britney isn’t scared one bit,” the insider said. “Her fans already know her truth.
She’s told her story, and nothing Kevin says can surprise her anymore.”
The source added that Spears’s team plans to quietly review the book so she’s aware of its content — but she won’t be reacting publicly to avoid damaging her fragile relationship with her sons.
“She doesn’t want to create more fallout with them,” the source explained. “That’s her priority.”
A Calm Response Strategy
Despite her reputation for being unpredictable online, Spears is reportedly determined to keep calm this time.
“She might vent one night on social media,” the insider admitted, “but she’s trying to stay quiet for her kids’ sake.”
Her current plan, they said, is simple — let the book release, let people talk, and then move on.
“She’s been advised to stay focused and let things play out naturally,” the source added.
Inside Federline’s Controversial Claims
Excerpts from You Thought You Knew were first published by The New York Times, and they include disturbing allegations.
Federline claims that during their marriage, Spears would sometimes stand in their sons’ bedroom doorway holding a knife while they slept.
“They would wake up to find her silently watching them,” he wrote, recalling one alleged moment when she said, “Oh, you’re awake?” before walking away.
Federline also claimed their sons later became afraid to visit her home, describing his growing fears that Britney was spiraling toward “something irreversible.”
Reliving One of Their Darkest Nights
Federline’s memoir revisits one of the most painful moments in both their lives — the night in 2008 when Spears was placed on a psychiatric hold at the Ronald Reagan UCLA Medical Center.
He described watching his ex being taken away as “one of the hardest nights of my life,” recalling, “This was someone I had loved, someone I built a life with — the mother of my children.”
That moment marked the beginning of Spears’s 13-year conservatorship, which ended in 2021 following the explosive #FreeBritney movement.
Federline’s Reflection on the “Free Britney” Movement
While Federline admits that the Free Britney campaign began with good intentions, he believes it also had unintended consequences.
In his memoir, he argues that the public backlash against her management team may have discouraged professionals from helping Spears afterward.
He even suggests starting a new movement — “Save Britney” — saying, “This is no longer about freedom. It’s about survival.”
“I’ve Never Been Against Britney,” Federline Says
In an interview with The New York Times, Federline insisted that his intentions have always been about protecting their sons and maintaining their relationship with their mother.
“I’ve never been against Britney,” he said. “But the truth is, my kids don’t know the woman I married, and I’ve spent 20 years trying to bridge that gap.”
Spears’s Past Statements on Her Marriage and Mental Health
In her memoir The Woman in Me, Spears denied having any serious substance issues, explaining that she only took Adderall for ADHD and struggled deeply with postpartum depression after giving birth.
She also accused Federline of painting her as unstable during their custody battles.
“Kevin tried to convince everyone I was out of control,” she wrote.
“He said I shouldn’t have my kids anymore — at all.”
Revisiting Old Wounds and Looking Ahead
Federline’s latest allegations echo claims once made by Britney’s sister, Jamie Lynn Spears, who wrote in her own 2022 memoir that Britney once locked them in a room while holding a knife — something Britney later called “crazy lies.”
The former couple married in 2004 after a whirlwind romance and divorced in 2006, with Federline later gaining full custody of their children.
The boys moved to Hawaii with him in 2023, but sources say they surprised their mother with a visit last Christmas — a small sign that their relationship may be healing.
In his upcoming memoir, Federline promises “intimate and transparent” details about their marriage and family life.
“I achieved my dreams, faced heartbreak, and endured ridicule,” he writes. “But I became the father my children needed.”
Meanwhile, Spears’s ex-husband Sam Asghari also weighed in, telling TMZ with a jab: “He was a professional father — so I guess his book will be about that.”
