"There are rumors going around about me that I have been kidnapped and held against my will," Katherine Jackson said. "I am here today to let everybody to know that I am fine."

"My children would never do a thing to me like that, holding me against my will," she added. "It's very stupid for people to think that."

At Katherine Jackson's side during the taped statement, which she read from a paper, were her children Rebbie, Jermaine and Janet Jackson. Also sitting next to her was Rebbie Jackson's daughter, Stacy, and a representative from the resort.

While reading the statement, Katherine broke off a couple of times and family members helped her find her place.

ABC News was not allowed to ask the family questions.

Katherine Jackson said a court ruling today that made TJ Jackson -- the son of Michael Jackson's brother, Tito Jackson, and grandson of Katherine Jackson -- the temporary guardian of Michael Jackson's children was "based on a bunch of lies."

She said her stay in Arizona at the Miraval was a "short vacation and rest."

"There's a lot of lies that have been put out there and I am going home to straighten them out, and this kind of stuff doesn't make sense," she said.

As for not calling her grandchildren for days, Katherine Jackson said, "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."

Katherine Jackson's son Randy said in an earlier interview that his sister, Rebbie, was with their mother at the resort and kept her cell phone with her. He said Michael Jackson's children knew they could call their Aunt Rebbie's phone to reach the group at any time.
