Lisa Marie's eight-year-old girls Finley and Harper Lockwood - the granddaughters of late rock 'n' roll legend Elvis Presley - are currently under the care of California's Department of Children and Family Services and will remain under their supervision until a trial next month after she allegedly found inappropriate pictures and videos on her estranged husband Michael Lockwood's computer.

According to the court documents, obtained and seen by, Lisa claimed as part of her ongoing divorce from her guitarist husband of 11 years that Beverly Hills Police Department found 80 of Michael's electronic devices during a raid on her home and, although they've seized the gadgets, they are still analysing the evidence she found.

She said in the papers: "I was shocked and horrified and sick to my stomach. My understanding is that Tennessee law enforcement is also conducting an investigation related to the photos and videos that I discovered.

"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."

The 49-year-old singer - who had an estimated fortune of $300 million but claims it's nearly all gone - also said in the papers that she has to pay for two nannies to go along with her estranged husband to monitor him thoroughly when he visits their children.

Lisa and Michael - who got married in a ceremony worth $340,000 in Japan in 2006 - separated in June last year and have been locked in a bitter divorce ever since.

The brunette beauty - whose mother is Priscilla Presley - cited "irreconcilable differences" for the reason behind their split and has reportedly requested full custody of their girls.

Michael, 55, then requested that his wife pay him $40,000-a-month spousal support and $100,000 toward his legal costs.

Lisa doesn't think she should have to pay the musician anything and has revealed she too is strapped for cash and doesn't know if she can afford her divorce lawyer Mark Gross.

She said: "I am hopeful that I will be able to pay Mr. Gross $5,000 per month over the next three months to maintain his representation through the hearing."

She's also been forced to move in with her 27-year-old daughter Riley Keough, whom she has with her ex-husband Danny Keough, because of her financial woes.

Lisa also has 24-year-old son Benjamin with Danny and was previously married to Nicholas Cage from 2002 until 2004 and the late Michael Jackson in 1994.
