Lisa Marie Presley Expecting Twins

Lisa Marie Presley is pregnant with twins, the singer's mom, Priscilla has confirmed to Entertainment Tonight.

"She wanted it really to be kept a secret for a long time, you know, and I think women should, because they should be able to announce what they're having and when it's time to make the announcement," Priscilla tells ET.

Lisa Marie's legendary dad, Elvis, was a twin, and her mother, Priscilla, has younger brothers who are twins.

Lisa Marie, 40, and her husband, rocker Michael Lockwood, 47, will greet their babies in the fall.

A source close to Presley tells Us Weekly, "She's never been so happy!"

Lisa Marie — who wed Lockwood in 2006 — has two children, Danielle Riley and Benjamin Storm, from her marriage to Danny Keough.
