Katherine and Joe Jackson have already done a sit down interview with Oprah Winfrey ... and Randy Jackson is livid about it.

Contrary to reports that Randy organized the interview, a source close to Randy tells X17online exclusively:

    "Randy had absolutely nothing to do with the Oprah interview. If he would have known about it, Oprah never would have been able to step a foot inside the house. The story about Katherine being Randy's puppet is obviously BS. Randy thinks Oprah tried to influence the jury during Michael's molestation trial. He is beyond pissed at this situation."

Randy, himself, released the following message:

    "I know everyone wants to know my position on the Oprah interview. First let me say that I love my mother and father. I am humbly grateful to have them as my parents, but i don't always agree with the choices they make. This is one of those times. I found out Oprah was at our family home ... my stomach ached and it still hasn't gone away. I had no prior knowledge this was going to happen. It was deliberately kept from me because they knew I would have tried to stop it.

    I know how Oprah feels about my brother and family. I also know that he would not have wanted this. In fact, she is the last person on earth he would want around his children. I can never forget when she had the show on pedophilia during the jury deliberation process in my brother's Santa Maria case. That was no coincidence."

Oprah's reps and Harpo have not been available for comment.
