Kevin Federline is concerned that Britney Spears is not getting stronger.
The DJ — who was married to the “Sometimes” singer from 2004 to 2007 and shares sons Sean Preston Federline, 20, and Jayden James Federline, 19 — writes in his upcoming memoir “You Thought You Knew” (out Oct. 21) that he is concerned for his ex’s health and well being.
“The truth is, this situation with Britney feels like it’s racing toward something irreversible,” Federline writes in the memoir, per an excerpt published in The New York Times Oct. 14. “It’s become impossible to pretend everything’s OK.”
The 47-year-old added, “From where I sit, the clock is ticking, and we’re getting close to the 11th hour. Something bad is going to happen if things don’t change, and my biggest fear is that our sons will be left holding the pieces.”
Federline — who is also dad to Kori, 21, and Kaleb, 19, with ex-fiancée Shar Jackson, as well as Jordan, 12, and Peyton, 9, with wife Victoria Prince —also shared details about his sons’ lives with Spears, 43, saying that they told him they did not want to go back to their mother’s house, in part out of fear.

“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,” he writes. “Then she’d turn around and pad off without explanation.”
E! News has reached out to Spears’ reps for comment.
The reality star also opened up about the January 2008 evening when the “Stronger” singer was taken to the hospital and placed under a 72-hour involuntary psychiatric hold after a three-hour standoff involving their kids, noting it was “one of the hardest nights” of his life.
“I felt sick over what she was going through,” he recalled. “This was someone I had loved. Someone I had built a life with. The mother of my children.”
Federline also questioned the 2021 decision to terminate Spears’ conservatorship, noting that the advent of the “Free Britney movement” — which was the push by fans to end conservatorship — “started from a good place,” but ultimately “vilified everyone around Spears.“
“All those people who put so much effort into that,” he added, “should now put the same energy into the ‘Save Britney’ movement. Because this is no longer about freedom. It’s about survival.”

Ultimately, Federline’s goal is to ensure that his sons are safe, asking anyone “who has ever been moved by Britney” to help her and their boys.
“Now, more than ever, they need your support,” he writes. “I’ve been their buffer for years, but now it’s bigger than me. It’s time to sound the alarm.”
Federline also got candid about his current relationship with Spears, telling the New York Times that while they “haven’t spoken in years,” he has “never, ever, once, been against Britney.”
“I’ve only tried to help my sons have an incredible relationship with their mother,” he told the outlet. “And it’s hard because when I really reflect on everything that’s happened — my kids do not know the woman that I married. And I’ve spent two decades trying to bridge that gap.”
