Lisa Marie Presley says she found "disturbing" images of kids on ex-husband's computer.

Lisa Marie Presley’s eight-year-old twin daughters have been placed in care, after she found indecent images of kids on their father’s computer, according to The Sun.

Court documents have revealed that Presley, the daughter of late singer and actor Elvis Presley, has claimed to have found “disturbing” images and videos on Michael Lockwood’s computer.

According to papers obtained by Mail Online, Finley and Harper Lockwood will be looked after by social workers until a trial in March.

Presley checked herself into rehab last August shortly after she and Lockwood split, and the allegations have emerged as part of their ongoing divorce.

“I was shocked and horrified and sick to my stomach,” Mail Online reports the 49-year-old said.

Mail Online says Presley claimed in the papers that the Beverly Hills Police Department found 80 of Lockwood’s devices during a raid on her home. She allegedly also stated that the police still have the devices and that they have not yet been fully analysed.

"My understanding is that Tennessee law enforcement is also conducting an investigation related to the photos and videos that I discovered," she said, according to the documents.

"I have no idea what else may be on those devices and fear that there are more and worse images and evidence in these un-analysed devices," she added.

Lockwood is yet to respond to the allegations.

Lisa Marie cited "irreconcilable differences” when she filed divorce papers last June, and sources claim that she asked for full custody of the twins.

Michael Lockwood is Presley's fourth husband. She has previously been married to Danny Keough, Michael Jackson and Nicholas Cage.

She has other two kids with Danny Keough, a son named Benjamin and a daughter Riley.

Presley has also claimed that she has been left struggling financially after losing almost all of her $300 million fortune.

According to the court papers, she has been forced to move in with her daughter Riley.

A trial regarding the allegations of sexual abuse has been set for March.
