Singer Lisa Marie Presley and her husband Michael Lockwood are expecting twins, Us Weekly magazine reported Tuesday.

Mother Priscilla Presley and former wife of late rock legend Elvis Presley confirmed to television show "Entertainment Tonight" the good news.

"She wanted it really to be kept a secret for a long time, you know." Us quoted Presley as saying to "ET". "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."

According to Us, Lisa Marie's dad Elvis was a twin, as well as her uncles on her mother's side.

Lisa Marie Presley, 40, wed Lockwood in 2006 and has two children from a prior marriage, Us said.
