Kevin Federline Claims Britney Spears Did Cocaine While Still Breast-Feeding

Kevin Federline claims he walked in on Britney Spears doing cocaine while she was still a breast-feeding mother during an explosive night that resulted in their divorce.

In his upcoming memoir, You Thought You Knew, Federline, 47, recalls Spears, 43, showing up to a 2006 release party for his album, Playing With Fire, despite having previously told him that she would be staying home with their two sons, Sean Preston and Jayden James.

“As we reached the top [of the venue], Jamie Spears, Britney’s dad, was standing there,” Federline writes. “I hadn’t expected to see him, so I was happy he’d decided to come support me. He threw a look my way, shook his head and motioned to my dressing room door. His expression sat in that flat blank space between disapproval and apprehension, as if to say: ‘She’s here, and it’s not good.’”

Federline remembers his security guard opening the door to find Britney sitting around a coffee table with her brother, Bryan Spears, her agent, Jason Trawick, and an unnamed “actress who was about to blow up from a role that would transform her life.”

“The first thing I saw was Britney and her young starlet friend snorting a fat line of coke off the table,” Federline alleges. “Both were wearing these outrageous wigs. Britney’s was electric blue. It was surreal. They didn’t even try to hide it.”

Federline writes that he was “stunned” Britney would use drugs when she was still nursing Preston and Jayden, who were only 13 months and 1 month old at the time, respectively. (The National Library of Medicine states that breast-feeding should be delayed at least 24 hours after cocaine use to allow the drug to be eliminated from the body.)

Federline claims he quietly confronted Britney later that night, saying, “Please don’t go home and breast-feed the kids like this. Call your mom or someone. We need to get formula. You can’t do this.” In turn, Britney allegedly threw a cocktail in Federline’s face in front of his guests and stormed out of the party.

“That was the proverbial final straw, the breast-feeding thing. Her reaction,” he writes. “That’s what ended us.”

Federline says he immediately asked his lawyer, Mark Vincent Kaplan, to send Britney a legal letter demanding that she stop breast-feeding their children. Days later, Britney had her own attorney, Laura Wasser, draft up divorce papers after two years of marriage.

“It all happened so fast,” Federline writes, “I couldn’t even catch my breath.”

Britney slammed the allegations in her ex’s tell-all in a lengthy X post on Wednesday, October 15, writing in part, “The constant gaslighting from ex-husband is extremely hurtful and exhausting. … Trust me, those white lies in that book, they are going straight to the bank and I am the only one who genuinely gets hurt here.”

Her rep also spoke out, telling Us Weekly in a statement on Tuesday, October 14, “With news from Kevin’s book breaking, once again he and others are profiting off her, and sadly it comes after child support has ended with Kevin. All she cares about are her kids, Sean Preston and Jayden James, and their well-being during this sensationalism.”

In an exclusive interview with Us on Wednesday, Federline denied his book is a cash grab, saying, “Money’s not the root of this thing. I feel like, if she has the right to tell her story, why don’t I?”

Us Weekly has also reached out to Bryan and Trawick for comment.

Notably, Britney was ordered to undergo random drug and alcohol testing during her divorce from Federline, which she passed. She also wrote in her 2023 memoir, The Woman in Me, that she “never had any interest in hard drugs” and had only abused Adderall, adding, “It was never as wild as the press made it out to be.”

Britney and Federline finalized their divorce in 2007. Later that year, he was granted sole custody of their sons.
