Britney Spears Says She First Learned About #FreeBritney Movement from a Nurse While 'Locked Up' at Rehab

The pop icon says her father made her spend more than three months in a rehab facility in 2018

Britney Spears first became aware of the #FreeBritney movement while in rehab.

In her upcoming memoir The Woman in Me, the pop icon, 41, writes that in 2018 she had been pushing back against her court-ordered conservatorship but had to endure further mental health evaluations and a stint in rehab.

“My father said that if I didn’t go, then I’d have to go to court, and I’d be embarrassed,” Spears writes, claiming that he’d make her look like an “idiot” if she didn't comply.

When Spears was at a $60,000-per-month Beverly Hills facility she was prescribed lithium and was only granted an hour of television before her 9 p.m. bedtime, she writes.

“They kept me locked up against my will for months,” the “Hold Me Closer” singer writes in the book. “I couldn’t go outside. I couldn’t drive a car. I had to give blood weekly. I couldn’t take a bath in private. I couldn’t shut the door to my room.”

While in the facility, a nurse showed the musician videos of fans who had organized to support her and were questioning the need for her conservatorship.

“That was the most amazing thing I’d ever seen in my life,” Spears writes. “I don’t think people knew how much the #FreeBritney movement meant to me, especially in the beginning.”

The release of The Woman in Me comes nearly two years after Spears was released from her court-ordered conservatorship, which had been in place for 13 years. The conservatorship was terminated in November 2021 after Spears gave fervent public testimony in court in June 2021.

Ahead of the book's release, Spears discussed it in an interview over email with PEOPLE.

“Over the past 15 years or even at the start of my career, I sat back while people spoke about me and told my story for me,” she says. “After getting out of my conservatorship, I was finally free to tell my story without consequences from the people in charge of my life.”

The Woman in Me will reveal “for the first time her incredible journey (and) strength at the core of one of the greatest performers in pop music history” and “illuminates the enduring power of music and love — and the importance of a woman telling her own story, on her own terms,” according to a press release from Gallery Books.

The Woman in Me is due Oct. 24 via Gallery Books, an imprint of Simon & Schuster. It is now available for pre-order.
