DMX -- I Have a Bone to Pick With Oprah Over Drug Interview

DMX says the Oprah Winfrey Network tricked him into spilling his guts during a recent interview -- in which the rapper came off as erratic and strung out -- and now he's out for revenge.

DMX is furious over his sit-down with Iyanla Vanzant on her show "Iyanla: Fix My Life," which aired on OWN. During the chat Iyanla asked X about his rampant drug use and he didn't hold back -- appearing unhinged.

But DMX tells us ... Iyanla pulled a fast one. She was supposed to ask him about his addiction to WOMEN ... not drugs ... and the dope questions were NEVER cleared beforehand.

He says, "Iyanla set the whole thing up to make me look bad for ratings," adding, "That lady is toxic ... My last words to her were that she can suck my d**k and she still can."
