TJ Jackson temp guardian of Michael Jackson's children. Katherine temporary suspended.

Katherine Jackson has been temporarily stripped of her guardianship over Michael Jackson's three children, and an L.A. judge just appointed Tito Jackson's son, TJ to become the temporary guardian, TMZ reported.

TJ Jackson and his lawyers has just arrived at the courthouse along with an army of lawyers -- his lawyer, along with Michael Jackson's children's lawyer, lawyers for the Michael Jackson's Estate, and lawyers for Katherine Jackson. Talk about one expensive hearing.

Judge Mitch Beckloff advised TJ and his lawyer, Charles Shultz, to seek a permanent guardianship, after hearing stories that Katherine may have been held against her will "from third parties."  Translation -- Randy, Janet, Jermaine and Rebbie.

Before handing down the ruling, TJ's lawyer told the judge TJ got a strange phone call from Katherine yesterday.  TJ said, "I've never heard my grandmother talk like that."  TJ added, "She wasn't sharp.  The pauses, choice of vocabulary ... she has not used certain phrases like that before."  TJ thought she was talking in code.  TJ choked up as he addressed the court.

Katherine Jackson called her home in Calabasas at 2 AM today and again at 4 AM, sounding "drugged" and ordering that the security team be fired and replaced by Janet Jackson's security, TMZ has learned.

A lawyer in court today made reference to "an incident" last night -- this is the incident.  Sources involved in the situation tell TMZ, people in the house were "alarmed and nervous" after hearing Katherine sounding heavily drugged.

In addition to attempting to 86 the security team, Katherine ordered Trent Jackson off the property. You may recall, Jackson's security -- and Trent in particular -- thwarted Monday's attempt by Randy, Jermaine and Janet to take the kids to Arizona.

Our sources say the prevailing view is that Randy and company have drugged their mom.

We're also told Jackie Jackson is furious at his conspiratorial siblings for what they've done and what they are trying to do.

Katherine's lawyer, Perry Sanders, tells TMZ, "I'm waiting on Katherine to get back in town and I'm looking forward to getting a hold of her to ascertain what's been going on."

Randy Jackson has gone to Twitter ... claiming Katherine fired Trent and her security team at 9 PM last night ... NOT between 2AM and 4AM this morning. 

He makes no reference to allegations she was "drugged up" during the phone call ... but Randy does say he was on the phone with Rebbie when it all went down. 

Randy also claims TJ had ASKED Katherine for temporary guardianship last night ... but Katherine flat out turned him down ... saying, "NO TJ."

TMZ broke the story that TJ would make this move -- a move supported by Paris, Prince, and Blanket, as well as the Michael Jackson Estate.

The judge said Katherine was not suspended for wrongdoing, but that she was prevented from doing her guardianship by the third parties who are clearly Randy, Janet, Jermaine and Rebbie.

Katherine's lawyer, Sandra Ribera, added that she (Sandra) has been to the house several times recently and believes Katherine has been held against her will.

Katherine's lawyer, Perry Sanders, says he would vigorously oppose any move to permanently strip Katherine of her guardianship duties. 

Perry also says, when Katherine returns to L.A., he will  file a motion to reinstate her as guardian.
