Britney Spears says she first learned about the #FreeBritney movement from a nurse in a $60,000-per-month Beverly Hills rehab

• Britney Spears says she first learned about the #FreeBritney movement when she was in rehab.
• "That was the most amazing thing I'd ever seen in my life," the singer writes in her forthcoming memoir, "The Woman in Me."

Britney Spears says she first learned about the #FreeBritney movement from a nurse while she was in a $60,000-per-month Beverly Hills rehab. That's according to an excerpt from her forthcoming memoir that was published by The New York Times.

In the memoir, Spears writes that while she was at the facility in late 2018, a nurse showed her clips of her fans participating in the movement and calling into question the need for the star's conservatorship.

"That was the most amazing thing I'd ever seen in my life," Spears writes in "The Woman in Me," per The Times.

"I don't think people knew how much the #FreeBritney movement meant to me, especially in the beginning," Spears continues.

The "Toxic" singer was placed under a conservatorship in February 2008 after she had several public meltdowns. It left her with no control over her assets or personal decisions.

The #FreeBritney movement — which emerged in 2009 — was for years dismissed as a conspiracy theory, until Spears gave an explosive testimony at a conservatorship hearing in 2021, detailing the harm she said she suffered under the arrangement.

The singer also writes in her book that she was constantly surveilled and had limited freedom at the rehab center where she first found out about #FreeBritney, per The Times. She says she was kept to a 9 p.m. bedtime and was only allowed to watch one hour of television a day.

"They kept me locked up against my will for months," Spears writes, per The Times. "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."

Spears previously mentioned the rehab program during her 2021 conservatorship testimony. At the time, she said she paid "$60,000 a month" for the program, and that it was held in "a small home in Beverly Hills." It's unclear from media reports if Spears names the facility in her forthcoming memoir.

Spear's conservatorship lasted for 13 years until a Los Angeles judge ended it in November 2021.

Her memoir is set to be released on October 24.
