But it's more for publicity than anything else, one source suggested to Radar.
"Britney wants to get as much attention and money for pictures with her third wedding as she did for her second, which is why she is considering reaching out to Elvis' daughter, Lisa Marie Presley, to ask if she can be married in the Graceland Estate in Memphis, Tennessee," the source disclosed.
"Getting married at the home of the late king of rock and roll in an elegant Southern-style ceremony would certainly generate one-of-a-kind pictures that Brit already plans to make the front page of magazines around the world."
Wedding rumors swirled recently when Spears, who has dated legal firm employee Lucado for more than a year, was seen flashing a gold ring.
Although the couple has yet to tie the knot, a source said, Spears, the mother of sons Sean Preston, 8, and Jayden James, 7, from her second marriage to Kevin Federline, has big plans for her blowout third wedding.
"Not only would the Graceland location, now a tourist attraction, be a visually stunning place for Brit and Dave to tie the knot, but it would be a convenient trip for most of their extended families, who are based in the south," the source said.
"If Lisa Marie, who controls the Graceland estate, gives her okay, Britney will start her wedding planning with a vengeance."
But with her romantic track record, Spears, 32, who split from fiance Jason Trawick in Jan. 2013 before following in Elvis' footsteps and becoming a Vegas headliner, better hope she doesn't end up in the Heartbreak Hotel!
