LOS ANGELES — Britney Spears will not stand for ex-husband Kevin Federline's scathing claims about how she raised their two sons, writing on social media that the allegations in his upcoming book are part of his "constant gaslighting."

The "Stronger" and "Oops!... I Did It Again" pop star hit back at her ex-husband Wednesday evening in a statement shared to X and Instagram, writing that confronting his latest revelations has been "extremely hurtful and exhausting." The 43-year-old singer, whose conservatorship ended four years ago, said she has "always pleaded and screamed to have a life with [her] boys."

"Relationships with teenage boys is complex," her statement continued. "I have felt demoralized by this situation and have always asked and almost begged for them to be a part of my life."

Spears and Federline, 47, married in 2004 and divorced three years later after welcoming boys Sean Preston and Jayden James. Federline, a dancer, was awarded sole custody in 2008 when Spears was placed under a conservatorship. In excerpts from his incoming book "You Thought You Knew," Federline accuses Spears of consuming cocaine while she was still breastfeeding their second son. He also accuses her of holding a knife while she watched her sons sleeping and raises claims about the singer's alleged cheating and a physical incident.

Federline wrote that the alleged cocaine incident occurred in 2006 during the release party for his album, according to an excerpt shared with Us Weekly. "The first thing I saw was Britney and her young starlet friend snorting a fat line of coke off the table," he said in his book. He said he urged the pop star not to "feed the kids like this" and that she responded by allegedly throwing a cocktail in his face.

"That's what ended us," he wrote, according to Us Weekly.

In a memoir excerpt published by the New York Times, Federline alleged that their sons would awake "sometimes to find her standing silently in the doorway, watching them sleep" with a knife in her hand. "Then she'd turn around and pad off without explanation," he wrote.

In her social media retort, Spears said their sons "have always witnessed the lack of respect show by [their] own father for me" and added "they need to take responsibility for themselves." She claimed that she had seen one son for only "45 min in the past 5 years" and that the other has visited only four times since 2021. A judge terminated Spears' controversial conservatorship in November 2021.

"I have pride too," the Grammy-winning vocalist said, adding she intends to make herself more available to her sons.

Federline's book isn't the first time he dropped bold claims about Spears. He claimed in a 2022 interview with the Daily Mail that their sons had "decided they are not seeing her right now" and opted not to attend her marriage to Sam Asghari, whom she has since divorced. At the time, Federline also claimed the boys had taken issue with her scantily-clad Instagram posts.

"I try to explain to them, 'Look, maybe that's just another way she tries to express herself.' But that doesn't take away from the fact of what it does to them," he said. "It's tough ... I can't imagine how it feels to be a teenager having to go to high school" with those posts existing.

In response to those comments, Spears said she gave her sons "everything" and found Federline's claims "HURTFUL."

Federline's "You Thought You Knew" comes out Tuesday, two years after Spears published her memoir "The Woman in Me." Her book dished on topics including her struggles with drugs, her relationship with ex-boyfriend Justin Timberlake and her conservatorship.

Spears said on Wednesday that her ex-husband's "white lies in that book, they are going straight to the bank." She also urged followers to take tabloid reports about her mental health and drinking with a grain of salt.

"I am actually a pretty intelligent woman who has been trying to live a sacred and private life the past 5 years," she concluded her statement. "I speak on this because I have had enough and any real woman would do the same."
