Teen Mom star Farrah Abraham's dad is reportedly writing a very revealing tell-all book.

Michael Abraham said he's writing a book about his 22-year-old daughter that will expose "a lot of stories" and "some surprises," according to Life & Style.

Michael reportedly explained he'll talk about some Teen Mom moments that didn't air on MTV and also pen what really happened during Farrah's childhood.

"Farrah definitely hasn't read the book yet," Michael admitted to the magazine.

Farrah, a single mother to four-year-old Sophia, starred in four seasons of Teen Mom and had filmed a pornographic video entitled Farrah Superstar: Backdoor Teen Mom, which was created and sold in Spring 2013.

She also appeared on VH1 Couples Therapy earlier this year.
