Randy Jackson Upset About Neice Paris Been In A Psychiatric.

Randy Jackson is pissed that his niece, Paris Jackson, is confined in what he believes is a psychiatric hospital and thinks something really stinks ... but Paris' mom thinks he's delusional. He tweeted this yesterday evening, read tweets from bottom to top:

Debbie Rowe, Paris' mom, is livid at Randy and is telling friends that he doesn't know what he's talking about.  We're told Rowe said, "As usual, he's grossly misinformed. She's not in a psychiatric hospital. She said Randy is just bitter because no one wants him to testify in Michael Jackson's wrongful death trial because he's irrelevant.
