Celebrating the princess’s birthday is always a special occasion, but this year it’s even better because it’s going to be a wedding.
Princess Beatrix will be married to husband Sir Richard Branson on August 8 in Cardiff, Wales, according to the BBC.
The royal couple, who were previously married in 1962, are the first to be married in Wales.
The ceremony will take place on the Royal Mile, which is the location of the wedding.
The bride will be dressed in a traditional purple gown with gold trim, a white dress with a yellow lining and a gold band.
The groom will also wear a gold tie, while Princess Beatrices parents, Prince Philip, will take the lead.
They will be joined by Prince Andrew, Prince Harry, Prince William and Kate Middleton.
The event will be held on a large stage in front of thousands of onlookers.
The venue is expected to sell out in a matter of hours.
The wedding will be attended by the Queen, Prince Charles and the Duchess of Cambridge, and the guests will also be treated to a lavish reception by the Duke of Edinburgh and Princess Beatra of Spain.
