Britney Spears is hitting back at the shocking allegations her ex-husband Kevin Federline made in his new memoir.

In excerpts from his upcoming memoir You Though You Knew, which releases October 21, Federline made bombshell claims against his ex, such as accusing her of watching their kids sleep while holding a "knife in her hand" and voicing concerns that she is "racing toward something irreversible," People reports.

"It's become impossible to pretend everything's OK. From where I sit, the clock is ticking, and we're getting close to the 11th hour," he reportedly wrote, per the New York Times. "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."

However, a representative for the "Lucky" singer slammed the claims made by Federline in a statement to People, alleging Federline's new comments come as he no longer receives child support from his ex for their two sons, Sean, 20, and Jayden, 19.

"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," they said. "All she cares about are her kids, Sean Preston and Jayden James and their well-being during this sensation."

The rep added that Spears already "detailed her journey" in her own 2023 memoir, The Woman in Me.

Spears and Federline got married in 2004 and divorced three years later, welcoming their sons during that time. She later she moved on with now-ex Sam Asghari. The pair tied the knot in 2022 after six years of dating but split the following year. Their divorce was finalized in 2024.
