Eminem's grandmother is writing a book about her life and the controversial rapper's upbringing.

Berry Kresin told BBC Radio 1 that her book is still in manuscript form and she has not yet found a publisher.

"I'm not trying to get rich off my grandson," she said, "it's more to get the true story out of my grandson."

She has said that the book focuses on her own life as well as Eminem's childhood: "I think they're more interested in what happened to Marshall, but I have people out there that always ask 'grandmother, what about you?' - they want the whole life story."
