Corey Feldman claims that his childhood relationship with Michael Jackson was damaging to him.
The two became close after Feldman found fame as a young actor in movies Gremlins, Goonies and Stand By Me.
Feldman admits Jackson has helped many children by becoming a friend and mentor - but says the fallen King of Pop does more harm than good by dropping kids unceremoniously when he gets bored.
The 37-year-old says, "He did real damage in my overall life. I was a 12-year-old boy who was hurt by his family and ignored by people at school.
"Michael would sit and talk to me for hours and he would listen. Then he would get bored.
"The biggest thing that Michael's done to children is befriending the ones that are in need and then abandoning them.
"(He'd say) 'Hey, I love you, I'm here for you, anything you need, you call me, I will be there for you.' Then the very next day, the number's been changed. As a 12-year-old kid, that's a pretty hard one to comprehend."
And Feldman claims the hardships Jackson has suffered in recent years are payback for the pain he has caused: "That's the karma he's paying off now."
Feldman recently denied suggestions he was molested by Jackson as a child, following his and Corey Haim's shocking abuse revelations on their reality TV show.
