Priscilla Presley is offering more details of daughter Lisa Marie's custody battle, divorce and the twins who are caught in limbo.

Grandmother to the girls, Priscilla says the 8-year-old twins Finley and Harper have been in her care for more than nine months.

"It’s still a very family-oriented environment for them,” Priscilla, 71, said. “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."

She declined to comment about reports that Lisa Marie receives a monthly check for $100K from the estate of Elvis Presley, saying only: "This is very personal, and we’re still going through a lot of different scenarios. There’s been a lot of rumors, a lot of speculation, and a lot of everything which always goes along with these situations."

Lisa Marie filed court document last month, claiming her estranged husband Michael Lockwood had hundreds of inappropriate photos of the couple's twins on his computer and other electronic devices. The West Hollywood Police Department is investigating the issue, as is the Tennessee Bureau of Investigation. Lockwood's attorney rejects the claims, saying: "Mr. Lockwood and his lawyers believe that 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."

Presley and Lockwood were in court last week and a judge ordered Presley to pay $50,000 of Lockwood's attorney fees at a rate of $10,000/month. The requested spousal support was denied.

Presley and Lockwood married in 2006 -- it was Presley's fourth marriage -- and welcomed their twin daughters in 2008 and then she filed for divorce the following June. The former couple are due in court March 17.
