‘Scary’ Secrets Exposed! Inside Mel B’s Explosive Tell-All

They don’t call her Scary Spice for nothing.

Mel B is writing a memoir she said will “set the record straight” about her 10-year marriage to Stephen Belafonte and her dealings with “domineering, controlling men” that should have her exes quaking in their boots, RadarOnline.com has learned.

“Brutally Honest” will detail Mel’s journey to Spice Girls fame as well as her relationships.

“This book will show that abuse can happen to anyone,” Mel said of her memoir, due in November. “It is important that my three girls know how to break the chain of abuse.”

As RadarOnline.com has reported, the book will reveal the inside scoop on her dirty divorce from Belafonte — complete with details on the sex tapes, an alleged ménage à trois with the nanny, lesbian affairs, drugs, booze, abuse and more.

And while her film producer ex is expected to wage a desperate fight for a “gag clause” to muzzle her, Mel is ready for a fight.

“The controversies and scandals of the past year are enough for most autobiographies,” a friend confessed. “Mel doesn’t want to hold back!”
