Having the book to be published September later this year, Jamelia will reveal in it how she coped with model Jaclyn Evans' claims that she had enjoyed a two-months affair with footballer Darren back in 2006 while he was still dating Jamelia.

"I'm going to talk about it honestly," Jamelia told The Sun. "I'll talk about having to act as if everything is fine when really it was heartbreaking."
