"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.
