Mel B is set to include a gagging order in any future pay-off in her divorce to estranged husband Stephen Belafonte.
The news comes as British publication The Daily Star claims friends are urging the former Spice Girl to write a tell-all book about her turbulent relationship with the restaurant owner.
An insider said: ‘A second book would be an absolute sensation. Mel is a global superstar and has plenty more to write about.
‘Also, if she has incidents in her marriage which were less than palatable, then it would send out a strong message to other women suffering in difficult relationships.’
As well as juicy details about her now failed relationship, Mel is alleged to be pondering including revelations about her five-year lesbian love life prior to her marriage to Stephen.
‘Her family in Leeds is right behind her and think it would be a great idea for her to finally tell the world the truth about her marriage,’ the source adds.
Mel’s secret book plans come as her husband, who looked relaxed as he stepped out in his gym kit, prepares to launch a fight for a pay-off, arguing he sacrificed his career to support her as a talent show judge.
