PARIS - Two years after escaping her father's guardianship, Britney Spears recounts her years as a superstar who became a victim of her success in a highly anticipated memoir being published on Tuesday.
One revelation from "The Woman in Me" has already made headlines: With Spears saying she felt pressured into having an abortion while dating fellow popstar Justin Timberlake between 1999 and 2002.
"If it had been left up to me alone, I never would have done it," she writes. "It's one of the most agonizing things I have ever experienced in my life."

The publishers have kept a tight lid on most of the contents -- unsurprising since Simon & Schuster reportedly paid more than 15 million dollars for the rights.
It was not a risky bet, however -- the book is already topping the pre-sale chart at Amazon US. It is being released on Tuesday in around 20 countries and 10 languages.
"Reliving everything has been exciting, heart-wrenching, and emotional, to say the least," Spears told People magazine.

The emotional turmoil means the 41-year-old singer has only recorded a small section for the audiobook, leaving the rest to actress Michelle Williams.
"There are so many hard things to read in the news about my book," she wrote on her Instagram this week.
"Then I woke up this morning and said it's all relative... nothing really matters at this point."
Spears looks set to add a number one bestselling book to her list of artistic accomplishments.
