LOS ANGELES — A judge on Thursday delayed a guardianship hearing for Michael Jackson's children at the request of attorneys for the singer's mother and his ex-wife, Deborah Rowe.

The legal documents filed on behalf of Rowe and Katherine Jackson were not accompanied by any petition for custody by Rowe.

The hearing had been scheduled for Monday. Records show attorneys for both sides asked for the hearing to be delayed until July 13.

Another hearing scheduled for Monday on who will take temporary control of Jackson's estate will proceed.

KNBC in Los Angeles reported earlier that Rowe intends to seek custody of Jackson's two oldest children and will seek a restraining order to keep Jackson's father Joe away from the children.

Calls by The Associated Press to Rowe's attorney Marta Almli were not immediately returned.

Katherine Jackson currently has temporary guardianship of the children.

Rowe is the mother of Jackson's two oldest children, son Michael Joseph Jr., known as Prince Michael, 12; daughter Paris Michael Katherine, 11.

The mother of the singer's youngest child, son Prince Michael II, 7, has never been revealed.

Meanwhile, Los Angeles officials were holding closed-door talks about a possible event for Michael Jackson on Tuesday at a downtown arena, a person with knowledge of the situation said Thursday.

The event would take place at the Staples Center, home of the Los Angeles Lakers, said the person who wasn't authorized to speak publicly and requested anonymity.

It wasn't immediately clear if a funeral or a public memorial was being discussed for the entertainer — or both.

All talks were preliminary, and no decisions had been made, the person said.

Another site that has also been discussed for a Jackson tribute is the Los Angeles Memorial Coliseum.

The discussions were held as the federal Drug Enforcement Administration joining the investigation into Jackson's death, and Jermaine Jackson said he would be "hurt" if toxicology reports showed his younger brother abused prescription drugs.

"In this business, the pressures and things that you go through, you never know what one turns to," Jermaine Jackson said in an interview on NBC's "Today" show.

The circumstances surrounding Jackson's death last week have become a federal issue, with the DEA asked to help police take a look at the pop star's doctors and possible drug use. Allegations have emerged that the 50-year-old entertainer had been consuming painkillers, sedatives and antidepressants.
