The 71-year-old actress confirmed last month that she was looking after her daughter Lisa Marie Presley's eight-year-old twin daughters Finley and Harper whilst Lisa and her estranged husband, Michael Lockwood, were locked in an ongoing court battle.

Now, the 'Dallas' actress - who was a former partner of the late music legend Elvis Presley - has said the two children are "doing wonderful", and continue to spend time with both their mother and father.

Priscilla said: "It's still a very family-oriented environment for them. They've been with me for - it'll be over nine months. They're great. They're doing wonderful. They're living a great life. They see both their parents, and we'll see what happens."

And Priscilla also said the situation between Lisa Marie and Michael was "very personal", but insisted the court case was being handled with "dignity" for the sake of their daughters.

She told 'Entertainment Tonight': "This is very personal, and we're still going through a lot of different scenarios. There's been a lot of rumours, a lot of speculation, and a lot of everything which always goes along with these situations ... Nothing is sorted out yet. Everything is trying to be sorted out, and done with dignity and done with care, especially for the children."

Priscilla took to social media last month to address the "confusion, commotion and concern" surrounding rumours that the twins were under the care of California's Department of Children and Family Services (DCFS).

She said at the time: "There is lots of confusion, commotion and concern from all the talk circulating. 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 (sic)."

This news comes after 55-year-old Michael was accused of allegedly having disturbing and inappropriate photographs of children on his computer.

According to the court documents, Lisa Marie, 49, claimed the 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.

But the findings made her feel "sick to [her] stomach", and is nervous about other things they may discover.

Speaking previously in the papers, Lisa said: "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."
