Lisa Marie Presley: "Beyond Thrilled" for Twins

Lisa Marie Presley is "beyond thrilled" about being pregnant with twins.

Writing on her MySpace blog Friday, the singer, 40, says that she and rocker husband Michael Lockwood are "beyond thrilled and blessed, elated and saturated in happiness" over the twins they will welcome this fall.

Presley thanked fans for "all of the amazing positive energy and beautiful well wishes."

The pair will be the first children together for Presley and Lockwood.

Though Presley only this week confirmed that she's expecting twins, she admitted on her blog that "a few months ago" she let the news slip to Entertainment Tonight before she "begged them to edit that out and not say anything yet as I wasn't ready for it to be out there then."

Lisa Marie has daughter Riley, 19, a model, and Benjamin, 15, with ex-husband Danny Keough.

Twins may run in Presley's family: her dad, Elvis, was a twin, and her mother, Priscilla, has younger brothers who are twins.

Presley, who's due this fall, wrote that she is "not recording at the moment as there isn't much room for breathing and singing right now, most of that area has been taken up and I can't really sing a line without running out of air halfway though.

"Writing and recording will resume when the little occupants in there have decided to join the outside world," she explained.
