The daughter of The King is passing on her DNA to new celebrity babies.

Lisa Marie Presley is expecting twins with rocker husband Michael Lockwood!

Her mom, Priscilla, confirmed it 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 Presley said.

Genetics may have played a role. It turns out, Lisa Marie's dad, Elvis, was a twin, and her mother, Priscilla, has younger brothers who are twins.

Lisa Marie and Michael Lockwood 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 Michael Lockwood in 2006 — was previously married to Danny Keough and (briefly) to Michael Jackson and Nicolas Cage.
