Katherine Jackson seemed drunk when she finally spoke to Michael Jackson's children Tuesday night for the first time in more than a week, and it alarmed the kids because the devout Jehovah's Witness doesn't normally drink alcohol, Breaking Celebrity News is exclusively reporting.

As previously reported, the Jackson family matriarch is on her way back to Los Angeles from the swanky Miraval spa in Arizona, where she had been holed up for the last week with no telephone or computer access. Katherine likely won't go to the rental house that she had been living in with the children, but will instead head to the Jackson family compound in Encino.

"It's time to let cooler heads prevail right now and it's very likely that Katherine will be staying at the Hayvenhurst mansion for the short term," a source close to the situation tells Breaking Celebrity News. "When Paris spoke to Katherine last night she sounded like she was drunk. Paris repeatedly asked her, are you ok, and Mrs. Jackson was slurring her words. I was told that it appears that Katherine was given alcohol during the time she was staying at Miraval, and remember, it was stated in court today that she had recently been diagnosed with high blood pressure. Katherine is extremely upset and distraught to learn that she lost custody of the children, but is hopeful she will be re-instated as their legal guardian very shortly."
