She also sounds like she's full of crap.
Jackson just finished up an on-camera interview with "ABC News" ... and talked about the family drama that's transpired since she mysteriously ditched MJ's kids 10 days ago ... and wound up in Arizona.
"There are rumors going around about me that I have been kidnapped," Jackson said ... adding, "I am here today to let everybody to know that I am good and fine."
"My children would never do anything to me like that."
Sure they wouldn't ...
When asked why she felt it was OK to leave 3 minor children in a house without a guardian .. Katherine explained she just felt like taking a "short vacation."
"One reason I didn't call is I just gave up my phone and I didn't want to have any phone calls while I was here."
It's unclear why she didn't TELL HER GRANDKIDS FIRST!
Still, Katherine says ... "I am devastated that while I've been away, my grandchildren have been taken away from me, and I'm coming home."
So, we gotta ask ..
