Justin Bieber's mother is to release her memoir.

Pattie Mallette has signed a deal for her book 'Nowhere But Up: The Story of Justin Bieber's Mom' - which will tell of her experiences as a single parent in Ontario, Canada, where she raised the 18-year-old superstar.

Giving his blessing to the project, Justin will write the foreword in the novel while Pattie - who fell pregnant with her only child aged 18 - will reveal how she battled abuse and addiction in her childhood and teenage years before attempting suicide at 17.

Jennifer Leep, Editorial Director for publisher Revell, said in a statement: ''Pattie's story is a powerful Example of courage and determination that will inspire anyone who has faced struggles in life.''

Pattie, 37, now travels everywhere with her son, who says she doesn't let him get away with things just because he is famous.

He told BBC Radio 1: ''We argue yes, I think every parent and son argue, but I love my mom.

''The other day she cancelled my phone plan. We got into an argument about something stupid, and she was like, 'Give me the phone' and I was like, 'No', so she just went and cancelled it.''

The book is scheduled for a September 18 release.
