Britney Spears is allegedly panicking at the thought of Kevin Federline releasing his first tell-all.

According to Globe, Spears is convinced that Federline will detail their toxic marriage in his book. And what’s worse is that Spears and Federline currently have a strained relationship with each other.

“Britney’s desperate to get her side of the story out there and panicking over what Kevin’s going to reveal about her. They’re on very poor terms right now and she’s also very nervous about giving him ammo to come after her with when she does release her own life story,” the source said.

The source added that Spears has every right to worry about Federline’s tell-all since he plans to lift the lid not just on their failed marriage but also on their custody battle over their sons.

Federline has been granted custody of his children and they have also been refusing to see Spears. During an interview last year, one of Spears’ sons said that he will only talk to his mom after she gets better.

However, the tabloid also insisted that Spears wouldn’t go down without a fight. So, the minute Federline releases a tell-all, she would most likely do the same.

“Britney’s eager to tell her side of the tale and inked a book deal with a whopping $15 million advance, according to sources who insist the manuscript is complete and details 41-year-old Britney’s rise to stardom, emotional meltdown, and the fallout with her family,” the tabloid said.

However, one should take the tabloid’s claim with a grain of salt. It’s not true that Federline is planning on releasing a tell-all. If he is, it would be announced by more reputable sources.

And if a tell-all is indeed in the works, it is guaranteed that Federline would detail his feud with Spears. After all, he has already been talking about his failed marriage to the singer during his interviews.

As of late, Spears’ tell-all hasn’t been confirmed either. There are whispers that the “Toxic” singer could be working on something. But until it is confirmed by Spears herself or her management, everything is just based on speculations.

For now, Spears is enjoying a quiet life with her husband, Sam Asghari. The couple is allegedly trying to conceive their first child together.
