Priscilla Presley Says Lisa Marie Presley's Daughters Are in Her Care Amid Legal Battle With Estranged Ex

'The girls have not been in foster care and never will be.'

Priscilla Presley is setting the record straight.

The 71-year-old grandmother of Lisa Marie Presley's 8-year-old twin daughters, Harper and Finley, confirmed on Sunday that the children were in her care amid Lisa Marie's legal battle with estranged husband Michael Lockwood.

"There is lots of confusion, commotion and concern from all the talk circulating," Priscilla shared on Instagram. "Let me put this to rest... the girls have not been in foster care and never will be. The girls have been with me and will be until all this is sorted out."

In court documents obtained by ET, Lisa Marie alleges that "disturbing" photos of children were discovered on a computer belonging to Lockwood.

In the documents, Lisa Marie had claimed that the girls were in protective custody by California's Department of Children and Family Services following her allegations that she found "hundreds of inappropriate photos" and disturbing video footage on Lockwood's computer.

Lisa Marie says she was "shocked and horrified and sick to my stomach" upon finding the alleged photos, in the documents filed on Feb. 7 in Los Angeles. The daughter of Priscilla and Elvis Presley is also asking the court to thus deny Lockwood's request for $40,000 per month in spousal support and $100,000 for attorney's fees.

In a legal response filed on Feb. 14, Lockwood denied the claims, slamming Presley's "distasteful" attempt to damage his reputation.

"It is very unfortunate and inappropriate that Ms. Presley chose to file a one-sided, inaccurate version of the facts in the Family Law Court's publicly accessible files," Lockwood's lawyer, Jeff Sturman said in a statement to ET, denying the allegations. "Mr. Lockwood is not going to publicly disclose very negative information about Ms. Presley to retaliate… Therefore, while Mr. Lockwood denies the truth of what Ms. Presley chose to put in the press, he has no further statement at this time."

"In June 2016, the Beverly Hills Police Department was notified of alleged child abuse involving the Presley family. It was then determined the allegations stemmed from activity originating in the state of Tennessee," the Beverly Hills Police Department told ET in a statement. They also said that their assistance to the Tennessee Bureau of Investigation led to the seizure of several items pursuant to the warrant.

"At this point, the TBI has not opened an official case in connection to this matter," the Tennessee Bureau of Investigation told ET last week, while noting that review of potential evidence of a crime was ongoing.

After being married since 2006, Lisa Marie filed for divorce from Lockwood citing irreconcilable differences in June 2016.
