The mother of the boy accusing Michael Jackson (search) of molestation testified Friday.

The 36-year-old woman said she doesn't recall a private investigator telling her he was working for the pop star's then-attorney Mark Geragos, but believed instead that the PI worked directly for the singer.

The woman took the stand in a hearing at which Jackson's defense is seeking to exclude evidence seized from the private investigator's office on grounds of attorney-client privilege, as well as some items taken from his Neverland Ranch (search) during a search.

The accuser's mother made the sign of the cross after entering the courtroom. She glanced briefly at Jackson, 46, who stared at her throughout her testimony, but she did not look back at him.

Flanked by Jackson, sister LaToya Jackson and mother Katherine Jackson, the pop singer's lawyer said after the hearing that his client has been exploited "since he was a little boy" and has been dogged by numerous "frivolous lawsuits."

Attorney Thomas Mesereau Jr. called his client a "musical genius" and said he's donated millions to needy kids around the world because the singer has been "devoted to healing children."

"The false charges he is facing will be battled in a court of law within our justice system," said Mesereau. "He is innocent and will be vindicated."

Jackson quietly said "Peace" as the brief press conference ended before opening his now-trademark umbrella and heading through the cheering crowd. He stopped to smile and exchange a few words with fans.

Earlier Friday a white-suited Jackson arrived in court with his family in tow for another hearing Friday amidst crowds of screaming, sign-toting fans.

Once again, most of the Jackson clan, including Janet and LaToya, were dressed theatrically in white. Jackson also wore a gold armband, and waved to fans as he strode confidently into the building.

One woman supporting the prosecution held a sign that said "We Support the Victim."

Jackson's attorneys are trying to show that the accuser's mother and prosecutors should have known that private investigator Bradley Miller (search) was working for Jackson's then-attorney Mark Geragos (search) when authorities seized items from Miller's office.

During questioning of the woman, Mesereau referred repeatedly to a transcript of an interview between Miller and the mother on Feb. 16, 2003, just days after her young son appeared with Jackson on a television special.

Mesereau noted that the transcript said Miller told her at the beginning and end of the interview that he was a private investigator working for "specifically an attorney named Mark Geragos who works for Michael Jackson."

She would not answer directly when Mesereau repeatedly asked if the document was false.

"I'm not denying it was said. I'm saying I don't remember," the woman testified.

The woman said she believed Miller was Jackson's private investigator because someone named "Frank" had told her so before she met Miller. She did not further identify "Frank."

Mesereau occasionally seemed exasperated when the woman said she didn't understand some of his questions.

When he asked if Miller had told her he worked for Geragos, she repeatedly said of Miller, "He's your guy."

At one point Superior Court Judge Rodney S. Melville directly asked her whether she believed the transcript was false. She repeated that "Frank" had told her Miller was part of Jackson's security team and was Jackson's private investigator.

On Thursday, Jackson's defense attorneys played video recordings of the Neverland search, arguing that law enforcement officers overstepped their bounds by taking items not covered in a search warrant.

Jackson has pleaded not guilty to child molestation, conspiracy and administering an intoxicating agent, alcohol.
