Britney Spears was reportedly prevented from performing with a music icon, according to an alleged leaked extract from her upcoming memoir.
The 41-year-old has yet to release her memoir, but supposed leaked details hint at some huge revelations from her time under her strict conservatorship by her father Jamie Spears.
The conservatorship, which was set up in 2008, controlled aspects of Britney's life including her finances, personal life and her music career.
