Britney Spears shares sister Jamie Lynn Spears' 'cruel' response when she asked her for help

Britney Spears' highly-anticipated memoir, The Woman in Me, has finally been released and fans all over couldn't wait to sink their teeth into it.

The book, which came out today (24 October), is said to be a 'brave and astonishingly moving story about freedom, fame, motherhood, survival, faith, and hope'.

Opening up about two decades of little-known details about the 41-year-old pop icon's life, Spears candidly discusses a whole plethora of things including her relationship with Justin Timberlake, her 'passionate' fling with Colin Farrell and the real reason she shaved her head back in 2007.

In the memoir, Spears also revealed her younger sister Jamie Lynn Spears' response when she asked her for help a few years back.

The book's official blurb reads: "In June 2021, the whole world was listening as Britney Spears spoke in open court.

"The impact of sharing her voice—her truth—was undeniable, and it changed the course of her life and the lives of countless others.

"The Woman in Me reveals for the first time her incredible journey—and the strength at the core of one of the greatest performers in pop music history."

It continues: "Written with remarkable candor and humor, Spears’s groundbreaking book illuminates the enduring power of music and love—and the importance of a woman telling her own story, on her own terms, at last."

In the book, Spears recalls the involuntary trip she was made to take to rehab a few years back in early 2019.

She wrote: "My father said that if I didn't go, then I'd have to go to court, and I'd be embarrassed."

The 'Everytime' star also revealed she was prescribed lithium and was kept there 'against [her] will' for months on end.

"I couldn't go outside," she continued. "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."

The mum-of-two opened up about reaching out to her sister, 32, from the facility.

According to Spears, the Zoey 101 star simply told her: "Stop fighting it. There's nothing you can do about it, so stop fighting it."

Spears, who clearly felt let down by her sibling, penned: "I didn't understand how Jamie Lynn and our father had developed such a good relationship.

"She knew I was reaching out to her for help... I felt like she should have taken my side."

The Woman in Me is now available to purchase after being released today (24 October).
