The Bulletin learnt from sources close to Catherine Zeta-Jones' parents and family in Wales that the Welsh actress and Michael Douglas are planning to marry on their joint September 25 birthday in Majorca. Apparently all the wedding depends on is the birth of their first child which is expected in four to five weeks time. Sources said yesterday that providing the birth goes smoothly, then both Catherine Zeta-Jones and the baby will be in condition to fly by September. Both the Hollywood couple and her parents have visited Bellver Castle in Palma with regards to a possible location for the wedding, but there is nothing to stop the marriage being held on Michael Douglas' Valldemossa estate. The rift over the pre-nuptial agreements has also been resolved and Douglas is said to be ready to sign next week as the couple get ready for the arrival of their first child which is said to be a boy. When Catherine was in Majorca a month ago she was spotted buying baby clothes for boys in a Palma department store. What gave it away was that the clothes were in colours traditionally associated with baby boys. Work started on making tentative plans for a Majorca wedding soon after they were engaged although Wales still apparently has its fingers crossed.
