(FILES) Official picture of US actress Grace Kelly and Prince Rainier of Monaco during their wedding ceremony in Monaco on April 19, 1956. Prince Albert and his South African fiancee Charlene Wittstock, an Olympic swimming star, will celebrate their wedding over two days on July 2 and 3. In Monaco, commentators are convinced that the marriage of Prince Albert will be an even bigger event than his parents’ 1956 wedding, which saw prince Rainier tie the knot with US film star Grace Kelly.
