LOS ANGELES (AP) _ A judge on Wednesday gave a freelance journalist 20 days to identify a source who he said told about a videotape allegedly depicting Michael Jackson having sex with a 13-year-old boy.

Under California Shield Law, writer Victor Gutierrez lost his right to keep the source confidential because Jackson's attorneys have not been able to find information about the purported tape, Superior Court Judge Reginald Dunn said.

Jackson alleged in a $100 million slander suit filed in January 1995 that Gutierrez lied about having access to the purported 27-minute tape.

Robert Goldman, a lawyer for Gutierrez, said his client is out of the country working on a book about the self-proclaimed King of Pop and the boy who sued him based on allegations of child molestation.

``After analyzing the court's ruling he'll decide on whether to comply or whether to continue to maintain the confidentiality of his sources,'' Goldman said.

An investigation of the pop star began in August 1993, when the then-13-year-old boy claimed Jackson had sex with him several times during a five-month relationship that year.

The boy's lawsuit against the singer eventually was settled for millions of dollars. No criminal charges were ever filed.

Jackson's suit also named the television magazine show ``Hard Copy,'' its parent, Paramount Pictures Corp., and reporter Diane Dimond, who presented a January 1995 report concerning the tape.

Also Wednesday, a federal magistrate ordered Jackson to be deposed for a second time in a breach of contract lawsuit filed after the ``Jackson Family Honors'' television special. The magistrate agreed to Jackson's request to be questioned in a hotel room where his guards can secure the building.
