Priscilla Presley is caring for her granddaughters as their mother Lisa Marie Presley and father Michael Lockwood battle in court.
The 71-year-old treated the twin 8-year-old girls to a day of beauty at Rossano Ferretti HairSpa in Beverly Hills.
Last week news broke that inappropriate photos and video of children were allegedly found on Michael's computer.
He and Lisa Marie are currently going through a nasty divorce and custody battle and their daughters have been removed from the home.
Priscilla made a statement about her family situation. On Facebook she wrote, "There is Lots of confusion, commotion and concern from all the talk circulating."
She continued, "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."
