Britney Spears is worried after it was revealed that her ex-husband, Kevin Federline, will reveal all about her in his upcoming memoir.

According to Radar Online, journalist Daphne Barak claims that the backup dancer plans to write about his experience as a father of two and share it with the princess of pop.

The worst part is that Britney’s father, Jamie, is said to have agreed to help Kevin with the venture.

The insider claimed:

“Once that happens, Kevin is free to divulge all – and he knows everything.”

Kevin and Britney have had disagreements about how to raise their two children. He even posted old recordings of the “Womanizer” hitmaker yelling at her two boys in the car on Instagram to criticize his ex-parenting wife’s skills.

He admitted to Sean and Jayden that they hadn’t seen their mother in months a few months ago.

Kevin has previously spoken about Jamie’s conservatorship of Britney Spears, which recently ended. The experience was “hard to witness, harder to live through, and worse to watch my boys go through than anything else,” he said.

In addition to the highly anticipated book, Jamie Spears has spoken out about his daughter and the circumstances that forced him to place her in conservatorship.

According to Jamie, if the formal guardianship had not been established 13 years ago:

“I don’t know if she’d be alive.”

Since the contentious conservatorship ended, Britney has claimed that her father mistreated her for years while in charge. She even claimed that he hired a security firm to monitor her phone calls and messages.

Jamie also claimed responsibility for saving his daughter at her lowest point.

“For protecting her, and also protecting the kids, conservatorship was a great tool. Without it, I don’t think she would have got the kids back.”

It’s best to take Radar Online’s claim with a grain of salt because fans are still waiting for an announcement about a book that Kevin Federline will write.
