Priscilla Presley couldn't be happier to be a grandma again – and seeing double.
"My daughter just had twins, so that's a dream come true," Presley, 63, told Entertainment Tonight"
at a Dream Foundation
charity event in Santa Barbara on Friday.
"We are just thrilled," Presley said at the 7th Annual First Ladies for the grant-wishing organization, for which she is an ambassador. "It's been a real delight entering into the room and seeing these two little babies – it's been pretty terrific."
Lisa Marie Presley and husband Michael Lockwood welcomed twin girls
on Oct. 7 and named them
Finley and Harper.
Lisa Marie, 40 who already has two children – Riley, 19, and Benjamin, 16, by ex-husband Danny Keough – is "doing great" according to her mother. But for daddy Lockwood, fatherhood is a whole new experience.
"Father's a little nervous," Presley said of her son-in-law. "He's a first-time dad, so it's the most beautiful thing to watch the way he holds and carries the babies. It's so endearing to watch how delicate he is."
