Moakler also suggested that she filmed her part before Barker began his relationship with Kourtney Kardashian.
Moakler and Barker married in 2004 and divorced in 2008.
The former couple share two children, Landon and Alabama.

She hopes the book will help women better understand trauma and unhealthy emotional bonds.

She believes women can lose parts of themselves during troubled relationships or major life changes.
Her memoir will explore how they can find their identity and confidence again.
Barker will feature in some chapters, but Moakler stressed that he will not become the main focus of the book.
Instead, she wants readers to take away a message about personal growth and moving forward.
