Backstreet Boy Nick Carter, whose new memoir “Facing the Music and Living To Talk About It” is out now, appeared on Dr. Phil on Monday, where he spoke about how his family blamed him for his sister Leslie’s death.

Leslie died in February of last year from a suspected accidental overdose at the age of 25, and Carter told Dr. Phil that her death still haunted him.

“There's definitely a part of me that did blame myself,” he told the psychologist, and added that he felt responsible for his siblings because he was the eldest of the family's five children. Carter admitted on the show that he had a troubled relationship with his sister, and that he kept his distance from her prior to her death.

He also revealed that his family believes Leslie would be alive today if Carter had been there for her more, and this was one of the reasons he decided not to attend her funeral.

“Leslie and I had a very hard relationship our whole life. I wanted nothing but the best for my sister. When it happened, I lay on my shower floor for hours, torn, because I wanted to go to her funeral so badly. It was really tough for me,” Carter said.

“The reason I did not go... I started to get blamed by the rest of the family for her death,” he added.

“Facing the Music and Living To Talk About It” was released on Sept. 17 by Bird Street Books, and it details the 33-year-old singer’s struggles with a dysfunctional family and issues with addiction, for which he partly blames former girlfriend Paris Hilton in the book.

“Paris was the worst person in the world for me to hook up with,” Carter writes in the memoir, according to Radar Online. He said that the former reality show star “fed my worst impulses as far as partying” and his relationship with her “could've ended in tragedy.”
