In a new revelation from his forthcoming memoir, You Thought You Knew, Kevin Federline says he was caught off guard when Britney Spears made a late-night call to her ex, Justin Timberlake, the night before their wedding. He states that the call raised red flags and led him to question whether she was truly ready to commit.

Details from the Memoir & Interview
- Federline disclosed the moment during an interview with Entertainment Tonight, recounting that he told Britney he “wasn’t down to get married” if she was still emotionally attached to Justin.
- Britney’s response, according to Federline, was that she was giving Timberlake a “final send-off,” framing the call as closure rather than a leftover attachment.
- He admitted that at the time, he was head over heels — but he couldn’t shake the doubt that she hadn’t fully moved on from her past.
Reaction, Pushback & Media Spin
- Britney’s team quickly pushed back, accusing Federline of leveraging her name for publicity now that his child support obligations have ended.
- They also asserted that her priority has always been their two sons, Sean Preston and Jayden James, and that she finds the sensational claims trending in tandem with his book release concerning.

Context: Their Swift Marriage & Aftermath
- Britney and Kevin married in 2004, after a whirlwind romance that followed her short-lived Vegas marriage to Jason Alexander earlier that year.
- Their marriage lasted around three years before divorcing in 2007, followed by well-publicized custody disputes.
- Federline’s memoir is stirring renewed interest in that era, particularly his perspective on moments like this pre-wedding call that may have foreshadowed deeper issues.
