Michael Douglas and Catherine Zeta-Jones' romance blossomed in Majorca last summer, it was while on a week long break on the island that there relationship was revealed and brought to the public eye. Tomorrow night they will say I do in a match made in tabloid heaven and possibly bound for paparazzi hell. There is widespread speculation about the guest list and many are wondering if Wales's second most famous export after Zeta-Jones herself, the singer Tom Jones, is going to be among the invited guests, who could also possibly include Sean Connery, Jack Nicholson, who spent a long weekend playing golf with Douglas in Majorca two years ago with the trip being marred by an incident between Nicholson and a local Spanish tv camera crew, and Danny DeVito, who has also holidayed with his close friend Douglas in Valldemossa. Over the past 20 years, since he bought the estate built by the famous Austrian Archduke Luis Salvador at the turn of the last century, Douglas has brought a string of rich and famous people to Majorca and done his bit in promoting the island on his global travels. The couple, who share the same September 25th birthday, met at a film festival in France in August, 1998, began dating in March, 1999 with Douglas using his Valldemossa estate as the base for his wining, dining and golfing in Majorca, and got engaged last New Year's Eve. There were initial rumours of a Majorca wedding, the couple and Zeta-Jones' parents spent over an hour looking round Bellver Castle as a venue with Palma City Councillor Juan Bauza. They all loved the idea, but it was travel logistics which eventually ruled the island out. Douglas, who says Majorca is the most beautiful island in the world was accompanied by an expecting Zeta-Jones when he opened his Costa Nord culturalcentre in Valldemossa in April and she opened a Majorica jewellery collection at the centre.
