Jamie Lynn Spears Unfollows Kevin Federline For Exposing Her Private Texts About Britney In Memoir

Jamie Lynn Spears is taking issue with Kevin Federline , her sister Britney's ex-husband, for including her personal text messages about the "Circus" singer in his memoir, "You Thought You Knew."

Federline sent shockwaves through the pop culture zeitgeist in early October 2025 when shocking snippets from his book, alleging Britney Spears used illicit drugs and neglected her children, were made public.

According to a report from Us Weekly, Jamie Lynn, known for her role in the children's series "Zoey 101," unfollowed Federline on Instagram along with his wife, Victoria Prince, after he included scandalous text messages from the actress in his new memoir.

In his book, which became available for purchase on October 21, Federline wrote candidly about his marriage to Britney, which lasted from 2004 to 2007, and included horrifying allegations.

On the topic of his children, Preston and Jayden, Federline seemingly implied that Britney's alleged neglect also impacted other members of her family, including her younger sister Jamie Lynn, who reportedly expressed her sadness to Prince.

"Honestly, this makes me want to cry because I feel for those boys so much," the alleged text from Jamie Lynn read. "I'm her little sister by ten years, and I can't imagine what her actual children must feel like at times, but I am familiar with the feeling of being a dingy trying to survive in a wave caused by another's ship, feeling like you have to rescue yourself."

Federline, 47, wrote in his book that Jamie Lynn began resenting her pop star sister over how she treated her nephews, allegedly claiming the "Overprotected" singer was 'incapable of taking' accountability.

"I'm still trying to come to terms with how she could be so unaware of anything outside of herself," the alleged text from Jamie Lynn continued. "I spent my whole life based around what was best for Britney, and I never wanted to step on any toes as the little sister, so I quietly built my own life and career. I tried to be supportive, but in a way that was healthy for my own well-being."

But that's not all Jamie Lynn reportedly had to say about her older sister. Federline revealed that the actress allegedly sent another message to Prince, thanking them for taking such good care of Britney's children.

"Any parent who's actually raised their children knows that raising kids is the toughest job on earth, and you both are raising those boys and their siblings while also having to constantly protect and shield them from so much chaos that no one would ever understand unless they lived through it," the message read.

Jamie Lynn went on to shade her sister, accusing her of likely "never" thanking Federline and Prince for "raising her children and still being beyond gracious to allow her so many chances to take part in their lives, even when y'all had more than enough reasons to validate cutting that off."

According to a report from E! News, Federline touched on more than just Britney's alleged strained relationship with her two sons in his memoir. The DJ opened up about the breakdown of their marriage as well, writing that it all began to go downhill after Britney's alleged experience with cocaine at the release party for his 2006 album, "Playing With Fire."

"The first thing I saw was Britney and her young starlet friend snorting a fat line of coke off the table," Federline wrote. "It was surreal. They didn't even try to hide it."

Federline hinted that that wasn't Britney's first experience with the illegal substance, writing that he "had already asked her to stop doing that." He went on to say that after he asked Britney to reach out to her mom to get formula for the babies rather than breastfeeding that night, the "Toxic" singer allegedly threw her drink in his face.

"That was the proverbial final straw, the breastfeeding thing. Her reaction," Federline wrote. "That's what ended us. Was that the only thing? Or was it all the little things piling up? I don't know, but in that moment, it was like the world collapsed."

In a lengthy post on X, formerly Twitter, Britney responded to the accusations made about her in Federline's book, calling them "extremely hurtful and exhausting."

Britney seemingly acknowledged that the relationship between her and her children hasn't always been great; however, she claimed she's "always asked and almost begged for them to be part of my life."

She also appeared to put some blame on her children, revealing that one son has "only [seen] me for 45 minutes in the past 5 years," while the other has only visited "4 [times]" in that timespan.

Britney didn't stop there, though. She claimed the "white lies" in Federline's book are only making him and his family richer while she deals with the pushback.

She finished her post with a plea for her fans, writing, "I will always love them, and if you really know me, you won't pay attention to the tabloids of my mental health and drinking. I am actually a pretty intelligent woman who has been trying to live a sacred and private life [for] the past five years. I speak on this because I have had enoug,h and any real woman would do the same."
