Daily Star carried publishing consultant Marc Shapiro's statement that if Solange was willing to expose her famous sister's deepest, darkest secrets as well as those of Jay-Z, then the sky was the limit in terms of financial reward.
"Solange has always been in the background while Beyonce has been the golden girl. She's sick of feeling she's being held down and she's ready to fight back. Families have problems and we're no different.
"Jay-Z and Beyonce might not like her spilling their secrets in a tell-all book but she believes that might be what it takes to secure her financial future," a source said.
Earlier, in a statement regarding the incident, Beyonce said that every family had problems and they were no different, but refused to reveal the reasons behind them.
