Britney Spears’ ex-husband Kevin Federline is about to drop his tell-all memoir — but sources exclusively tell Star that two of her other exes are getting ready to follow suit, leaving the Princess of Pop in a panic.

“Poor Britney is distraught,” the source says. “She feels totally exposed and powerless to stop this.”

Federline — who was married to Spears from 2004 to 2007 — announced his “extremely intimate and transparent” book, You Thought You Knew, in August.

According to sources, “[Britney’s] terrified about what Kevin is going to write and how it will affect her kids.” (Federline and Spears share sons Sean Preston, 20, and Jayden, 19.)

“He’s said so many awful things about her over the years and always tried to paint her as the villain so she’s expecting more of the same from his book,” the insider continues. “It’s really impossible to emphasize enough just how upset this has got her.”

While the source notes that the “Stronger” singer, 43, is “sick over” the contents of Federline’s book, she’s reportedly also convinced ex-husband Sam Asghari is “plotting a tell-all of his own.”

“That’s the real reason he’s been so aggressive with Kevin,” the source adds, referring to Asghari’s recent comments about Federline being a “professional father.” “[Sam] sees him as competition.”

Following her divorce from Asghari, 31, in August 2023, Spears began dating her former maintenance worker Paul Soliz. The two were on-again, off-again before calling it quits for good in February.

“Paul Soliz has been sniffing around for a payday as well and he didn’t sign an NDA,” the source tells Star. “Everyone’s bracing for some big tell-all announcement from him, too.”
