The couple was issued the document, which boasts both stars’ signatures, following a 15-minute ceremony on May 26, 1994. The certificate will go up for auction at an estate sale by Philip Weiss Auctions in New York January 10.

Auctioneer Philip Weiss believes the keepsake will be a high-demand item due to an increased interest in the Thriller singer since his death last June.

“Anything relating to Michael Jackson is of extreme interest right now because of his untimely death and the release of the movie,” Weiss explains. “…When you have an item that combines his name and legend with the Presley name and legend, their marriage certificate no less, with both of their signatures on it, you’ve got something that’s almost impossible to predict what it will bring at auction.”

Lisa Marie Presley and third hubby Michael Lockwood showed off twin girls Harper and Finley for Hello! Magazine as Elvis’s youngest grands celebrate their first birthday.

“We want desperately to preserve their purity, love and trust for as long as we can before people and life cause the inevitable souring and contamination,” the rock princess said of her two youngest children.

“It is incredible that we all start out so pure, so genuine, happy and trusting.”

Lisa Marie is currently in the UK, where she hopes to move permanentl.

“We have found the quality of life so much more enriching and fulfilling,” she said of the country. “The people and its beauty have reawakened me and have smoothed out some of my bleak and jagged views about people and life.”

Lisa Marie Presley and her hubby Michael Lockwood are introducing their newborn twin girls, Finley and Harper, born last October, in the January 26 issue of PEOPLE Magazine.

In the issue on newsstands this Friday, Lisa Marie, 40, says the road to pregnancy was a long one, explaining that she resorted to taking blood thinners in hopes of becoming pregnant.

“We tried to get pregnant for two years. My blood was too thick and would clot, which caused several miscarriages. The moment I took blood thinners, I got pregnant.”

In a post titled “Now Is Not The Time,” new mother Lisa Marie Presley took to her MySpace blog on Tuesday to defend her controversial religion of choice, Scientology.

The blog was prompted by the recent wave of negative media attention surrounding the buzzed about faith in the wake of the death of John Travolta and Kelly Preston’s 16-year-old son, Jett, who passed away of a seizure in the Bahamas last Friday.

Some critics believe the family’s religious beliefs may have prevented Jett from receiving adequate medical care.

“I wished I could be writing you under happier circumstances but I cannot because Two of my very good friends, (John and Kelly Travolta ) the sweetest people in the world have just encountered the worst possible tragedy a parent could be forced to endure, the death of their son Jett,” Lisa Marie wrote on Tuesday.

“I am writing this because I have noticed that for the most part, people and the media have been very sympathetic and respectful, but there are those certain ones that want to use this horrible tragedy as an opportunity to once again, blame and or attack Scientology? Folks, as popular as it has been to discriminate and ridicule Scientology and Scientologist’s in the recent past, Now is NOT the time,” the star adds.

“Among most of the crazy made up garbage that goes around about it , It is not true that Scientologist’s ‘Don’t believe in’ medical care , medicine or medical Doctors and that may have something to do with this terrible tragedy. Just like anyone else, If one is sick , they go to the doctor, If a medication will make it better then they take it. If they don’t then they are an idiot and you can’t blame their religion.”

“Whatever medical and or physical condition Jett had, I can tell you first hand that his parents were on a tireless, never ending quest to get and provide him with the absolute best care anyone could ever ask for and need, Medically, physically, emotionally, medicinally and spiritually. I am not writing this to preach my beliefs, I am here to protect my friends,” Lisa Marie concluded.

“John and Kelly have done nothing but spend their lives and their time helping others, making people happy and making peoples lives better. Please let this family grieve in peace.”

“This was my dad, this was Elvis coming through!” the 40-year-old mother of four says of the spook session. “I would know his energy anywhere and this was him, I have no doubt,” Lisa Marie insists.

“Not only was it his voice, but I could also feel the exact same love that he gave me when I was a little girl. It was so overwhelming that I started to cry.”

“The medium comforted me with his words by telling me he was proud of me, the babies were beautiful, he’s doing just fine on the other side, he watches over me….We had this amazing talk.”

She adds, “The most comforting thing he told me is that even though he’s not here physically any more, he is still with me and he’ll watch over the babies too.”
