The mother of Michael Jackson's alleged child abuse victim lost her temper in the witness box yesterday and launched a verbal attack on the pop star.

Mr Jackson had managed to fool her, along with the rest of the world, but the truth was that he "didn't really care about children, he cared about what he was doing with children", said Janet Arvizo.

Her teenage son, Gavin, a former cancer patient, accuses Mr Jackson of plying him with drink and sexually abusing him when they slept together in Mr Jackson's bedroom in 2003.

The Arvizo family also accuses Mr Jackson's entourage of holding them against their will. The singer denies all the charges.

The jury in Mr Jackson's trial has heard how Ms Arvizo and her children stayed on Mr Jackson's Neverland ranch, and were given money and presents. Ms Arvizo said she now regretted this, and that she had been taken in.

"He has managed to fool the world and I was one woman inside there, that is what I was communicating," she raged, while being cross-examined by Thomas Mesereau, Mr Jackson's chief lawyer.

"What he puts out in the world is not who he really is. Because of this criminal proceeding, people know who he really is."

Ms Arvizo had admitted allowing her children to return to Neverland even though she was suspicious of the singer.

She has told the jury that the first time she became concerned was when she spotted the singer licking Gavin’s head onboard a private jet flying from Florida to California. She says she did not report it as she thought she was seeing things and no-one would believe her.

Mr Mesereau asked her how many times she had allowed her children to return to Neverland after the alleged incident.

He said: "Do you think it was four times you let your children go back to Neverland?"

She looked straight at the jury and replied: "They were there for the whole time. It was poor judgment on my part - I know that now."
