AceShowbiz - Britney Spears has finally spoken up and she tells all. Nearly two years since her conservatorship ended, she released her first memoir in October. Titled "The Woman in Me", the book quickly became a best-seller not without a reason. It is full of juicy stories that had been kept secret from public, including details of her relationship with Justin Timberlake.

The "Toxic" songstress claimed she had an abortion while dating the former NSYNC member because he "wasn't happy about the pregnancy" and claimed they "were way too young" to have a baby. She admitted to have cheated on Justin "one time" with choreographer Wade Robson. She, however, alleged that the "SexyBack" crooner cheated on her several times with "another celebrity."
