Michael Jackson’s mom wants custody of her late son’s three children.

Katherine Jackson has filed a petition in Los Angeles Probate Court seeking legal guardianship Prince, 12 and Paris, 11 — Jacko’s kids with ex-wife Debbie Rowe — and his youngest son, Prince Michael II, 7, who was born to an unnamed surrogate.

The petition states the kids have “no relationship with their biological mother” but they have “a long established relationship” with Katherine.

“Minor children are currently residing with paternal grandmother,” the petition states. “They have a long-established relationship with paternal grandmother and are comfortable in her care.”

The petition says it’s “not known at this time” whether [Rowe] agrees that Katherine should be the legal guardian.

The petition says the value of Michael’s assets are unknown at this time.

A hearing on the petition has been scheduled for August 3.

UPDATE: Katherine has been granted temporary guardianship of the three kids, TMZ reports.

Michael Jackson’s three children — Michael Joseph, Jr., Paris Michael Katherine and Prince “Blanket” Michael II — want to stay with their grandparents, it was claimed Saturday.

Jackson, 50, died Thursday after suffering an apparent cardiac arrest at his home in Los Angeles.

According to TMZ, the tragic star’s kids will continue to live with Katherine Jackson at the family’s Encino home.

The Jackson family is said to be 100 percent behind the decision — feeling that Katherine and Joe Jackson “are the only people who can help the children understand who their father was, help them grieve, and teach them to deal with life in the spotlight,” a source said.

TMZ also says the kids are healthy but, as expected, they “miss their daddy.”

Earlier today, Showbiz Spy reported that Jackson wanted his mother to raise his children if anything ever happened to him.

Joe and Katherine Jackson’s attorney, Debra Opri, told RadarOnline, “Katherine will be the custodial parent for the kids. It was understood that Katherine is the best person to take care of the children as she can provide a stable, loving environment for the kids. The children will remain with Katherine, and she should raise them.

“I believe she [Wacko's ex-wife Debbie Rowe] surrendered her custodial rights to the children, but I’m sure that this will eventually be heard in court or arbitration.”

It has also been claimed that Rowe wants custody of Prince Michael, 12, and Paris, 11, her two children with the late star.

“She said she was going to go for full custody of them,” a source said. “She said she was quite prepared to go all the way and fight him in court for it.”

Michael Jackson — who died Thursday after suffering an apparent cardiac arrest at his home in Los Angeles — wanted his mother to raise his children if anything ever happened to him.

“I believe she [Wacko's ex-wife Debbie Rowe ] surrendered her custodial rights to the children, but I’m sure that this will eventually be heard in court or arbitration.”

Opri also says the Jackson family is grieving and that the funeral for Michael will most likely happen within the week.

Jackson had three children — Michael Joseph Jackson Jr, Paris Michael Katherine Jackson and Prince Michael Jackson II.

Prince Michael, 12, and Paris, 11, are his kids with Rowe, who reportedly wants custody.

Michael Jackson’s family is already gearing up for a fierce custody with the late star’s ex-wife Debbie Rowe — she wants her kids back.

Rowe remains the legal parent to Prince Michael, 12, and Paris, 11, her two children with the late star.

Rowe apparently told a friend she wanted full custody of the youngsters — two days before Jacko’s death.

“Debbie threw a fit, saying she was sick of the way Michael was bringing the children up,” a source told British newspaper The Sun.

“She said she was going to go for full custody of them. She said she was quite prepared to go all the way and fight him in court for it.”

Rowe wed Jackson in 1996 (he was a patient in the dermatologist’s office, where she worked as a nurse). They divorced in 1999, but during their custody fight, she agreed to give up her parental rights, insisting Jackson was a good father.

Sources close to the Jackson family say Jacko’s elderly mum Katherine will “fight tooth and nail” to stop Debbie getting the youngsters.

They claim the former dental nurse signed away her parental rights in return for a house and a multi-million dollar lump sum.

“She understands there will be a vicious legal battle and she knows Michael’s mother will not readily hand the kids over to her,” the source added. (continue)
