Jennifer Hudson is struggling to strike a deal to publish her weight-loss book because the agents want her to open up about the murder of her mum, brother and nephew in 2008. Hudson had put herself into dieting and exercise following the birth of her son David in 2009 and lost 36 kilograms. She has been pitching a book about her weight issues and diet tips to US publishers, and wants $1 million (Dh3.67 million) for the deal, reports contactmusic.com. But the book bosses are interested in paying huge sum only if Hudson writes about coping with the brutal slaying of her family three years ago. "It was disappointing. Her book about her diet is really appealing and wonderful. But if you spend a lot of money on the book deal, you want it to sell. With no talk of her family, we didn't think it was worth it," said a source from the publishing house.
