Although they have not legally married yet, they have staged a special commitment ceremony in Greece to show friends and family how serious they are about each other. "It was nothing formal, they see it as their first step towards marriage," Stuff.co.nz quoted a source as telling the British edition of Grazia magazine.
"They both dressed up and said beautiful handwritten vows. They then exchanged rings in a spiritual service and drank shots before sitting down to a lovely private dinner at a tiny restaurant. They wanted to show that they are committed to each other and want to spend the rest of their lives together."
Gaga wore a long white Grecian-style gown for the event, but in her typical style it was given a twist. The dress was open all the way down the front with just a small gathering above her bellybutton, meaning her white knickers were fully visible. She accessorised with a chunky silver necklace, and wore her hair flowing around her shoulders. Luc opted for a white single-button jacket, teamed with zebra-print leggings.
"They are still planning to marry, but that will come later when she has the time to plan a big Italian-style wedding. She says he's the one and she doesn't want to lose him ever again," the source added.
It was recently claimed Gaga is keen to have a five-day party when she gets married, and wants Dita Von Teese to jump out of a cake and perform a burlesque routine. She also wants fireworks, and a series of lavish outfits. Gaga's publicist told the website E! News that the stories about her impending marriage are "completely untrue."
