In a halting, emotion-choked voice, the son of Michael Jackson's (search) former housekeeper testified Monday that the pop star molested him during a tickling game in 1990.

The 24-year-old man was called to the stand as prosecutors in the current molestation case against Jackson began trying to show the jury that the singer has a habit of molesting boys.

The witness said that over a span of several years, Jackson twice touched his groin over his clothes during tickling games at Jackson's Los Angeles (search)-area condominium, which he and his mother referred to as "the hideaway." He said that in a third incident, Jackson reached under his clothes at his Neverland (search) ranch.

Jackson gave him $100 after each of the first two incidents but nothing after the third one, he said.

"We were tickling. He was tickling and I was laughing and the — it was, he was — he was tickling me in the ...," the witness said before asking the judge for a break. He wiped his eyes and drank some water.

"He was tickling me. I was wearing shorts again. ... He reached on my leg and I'm still laughing and he reached up to my — privates," the witness said.

As he began to describe the alleged molestation he apologized to prosecutor Ron Zonen for his halting testimony and said: "This took a lot of counseling to get over, just to let you know."

The defense asked that the comment be struck from the record and Judge Rodney S. Melville agreed.

The witness said that Jackson touched him for two or three minutes and that he remembered thinking, "I should probably go." Asked whom he first told of the incident, the witness said, "Probably God."

The appearance of the young man was allowed under a ruling last week by the judge that prosecutors may present evidence Jackson molested or otherwise behaved inappropriately with five boys before the time period of the current allegations.

The judge told jurors the evidence of past uncharged crimes was being offered to show a "propensity" by Jackson to commit similar acts to the one with which he is charged and to illustrate a pattern of conduct leading up to possible sexual offenses.

He said they need not decide beyond a reasonable doubt whether those acts were committed but must decide their weight "by a preponderance of the evidence."

Jackson is on trial on charges of molesting a 13-year-old boy in February or March 2003.

In his ruling, the judge said prosecutors could mention that the housekeeper's son and another boy received civil settlements from Jackson but could not tell the jury the amounts. Prosecutors have said the housekeeper's son received $2.4 million in 1994.

The housekeeper's son, now married and working in an anti-truancy program, was asked at the outset of his testimony if he could identify Jackson in court.

"He's the light-complected gentleman," the witness said, smiling at Jackson.

The witness also described two earlier alleged incidents that involved Jackson touching him over his clothes.

"We were watching cartoons and he just started tickling me which was — cool," he said of the first incident, which he described as beginning while they were seated in a chair and then later on the floor.

"It eventually moved down to my little private region, I guess ... around my crotch area. You know, you're 7, you didn't think it was wrong. ... I probably did think it was weird but not super-weird because you were tickling," he said.

In another incident, he said, Jackson began tickling him as they were cuddling on top of a sleeping bag while watching cartoons. He described the tickling proceeding in the same way.

The witness said he never talked about the incidents with anyone until 1993, when investigators came to him after another boy made allegations against Jackson in a civil case. The other boy also would later receive a settlement, reportedly in the multimillion-dollar range. No criminal charges were filed in either case.

On cross-examination, Jackson attorney Thomas Mesereau Jr. sought to show that the witness' mother had a financial interest in his story, asking if she had received $20,000 to appear on the television show "Hard Copy."

The witness said he learned of the payment just days ago, but saw the show when it aired.

The witness also testified that he told police he tried to block out the memory of the tickling episodes. "I didn't want to ever talk about this stuff again," he said.

Mesereau inquired whether police had once asked the witness, "This is what happened, right?" to which the witness allegedly replied, "I'll have to work on that."

The young man said he had no memory of making that statement.

The witness also was asked why, when he first talked to police, he denied anything had happened. "I was scared," he replied.

Jackson fans who showed up over the weekend to rally on his behalf also stayed for Monday's court session, chanting and shouting when he arrived and later as he went home for the day.
