Kate Moss is reportedly planning to tie the knot with Nikolai von Bismarck in Greece. The 42-year-old supermodel and 29-year-old aristocrat's recent trip to Hydra is believed to inspired the blonde beauty to want to hold a "low-key" ceremony on the Saronic Island. However, plans to get married will only take place once Kate's divorce from her estranged The Kills rocker husband Jamie Hince, 47 are finalised. A source told The Sun newspaper: "Both want a low-key ceremony with a handful of friends and family. The plan is to head back to London to celebrate with a larger group. "They fell in love with Greece after jetting there last month and got the ball rolling by planning the wedding while out there." Meanwhile, friends of Kate are said to be worried that Nikolai isn't right for her and that he is leading her astray after she started drinking again, following three months of sobriety. The source added: "They are a volatile couple. He took her late-night drinking and they argued several times. Her pals are concerned he's leading her off the straight and narrow." The decision to get married in Greece comes after Kate spent part of her 2011 honeymoon with Jamie in a yacht off the coast of Kefalonia. The trip was wrought with danger after a tremor struck a nearby island. A source at the time said: "People on the shore were alarmed, but Kate and Jamie's boat has been rocking all week so they may not even have noticed. "They are clearly having the time of their lives and look totally in love."
