US publishers have offered 12 million pounds to Solange Knowles to dish out the dirt relating to the elevator brawl with Jay Z.
Publicist consultant Marc Shapiro said that if Knowles is prepared to expose her sister as well as brother-in-law's deepest, darkest secrets then the sky is the limit in terms of financial reward.
Sources confirmed the news that the 27-year-old singer has always been in the background while Beyonce has been the golden girl but now she is sick of it and wants to fight back because that might only be the way to secure her financial future, the Daily Star reported.
The 'Single Ladies' singer earlier gave a statement regarding the incident that every family has problems and they are no different but refused to reveal the reason for it.
