Dr. Drew talks to Mötley Crüe founding member, mega rock star Nikki Sixx on Thursday's show. Drew will be discussing his new book and album called “This Is Gonna Hurt: Music, Photography And Life Through The Distorted Lens Of Nikki Sixx", which takes us on a journey of beauty and how we as a society view it. Also, Drew is going to get to the truth about how Nikki overcame his very serious addiction to heroin.

Then, Dr. Drew sits down with author and award winning journalist Tracy Ross who has written a new book, “The Source of All Things,” chronicling the sexual abuse she suffered at the hands of her stepfather, Donnie Lee. Tracy opens up about her painful childhood and how she had the courage, years later, to confront Donnie and have him admit to the abuse. Donnie joins the conversation to explain why he felt compelled to expose his dark past and how it is now helping him repair his relationship with his stepdaughter.

Plus, Dr. Drew takes your calls and questions!

It all happens tonight on HLN at 9 p.m. ET/PT.
