It came at the same time his bride-to be Kate Middleton revealed that her sister Pippa is set to be the maid of honour.
The general public are not lucky enough to be invited to the ceremony at Westminster Abbey; however, London still possesses some of the World's top tourist attractions.
Mayor of London Boris Johnson has invited UK residents and tourists from around the world to take a trip to the capital city for the royal wedding vows.
Around 600,000 extra visitors came to the city during the 1981 wedding of Prince Charles and Lady Diana and hundreds of thousands are expected this time around too.
If you decide to visit some London attractions during the royal wedding weekend - with April 29th now a public holiday this year - you will most certainly be in good company.
But don't worry about not having anywhere to stay.
The tourism body says there is still a wide range of accommodation available, so you should not believe the rumours that everything is booked up.
Of course, if you plan to visit London's attractions during the royal wedding, you might want to book accommodation as soon as possible to avoid being left disappointed.
Over 100,000 hotel rooms can be found in London, Visit London assures - although not all will be available- so book well in advance if you do not want to miss out on the royal wedding procession past landmarks including Buckingham Palace.
Visit London reports the mayor as saying that there will be a really exciting atmosphere in the city during the celebrations.
And with world-famous London attractions to also keep visitors occupied during their stay, there may be no better time to see what the capital has to offer.
Mr Johnson asserts that whether you decide "to spend a week, the weekend or just come for an overnight stay, London promises a warm welcome and an unrivaled array of hotels, restaurants, shops, museums and major attractions to ensure a truly memorable experience".
Chairman of the London Regional Committee of the British Hospitality Association Ciaran Fahy said: "London has a huge range of value accommodation and with our excellent transport links people can find exceptional value rates a few Tube or bus stops away from the centre of London, particularly in Docklands and in either east or west London.
"It's worth remembering that Buckingham Palace is only 40 minutes from Heathrow.
" He added that many five-star hotels that are found near Buckingham Palace are only offering packages where people have to stay for a set number of nights.
However, this could provide you with plenty of time to not only catch the royal wedding, but also to explore some of the other things to do in London.
Buckingham Palace is one place you may not want to miss whether a royal wedding is taking place in the capital or not.
With 775 rooms, the palace has been the official home of Britain's sovereigns since 1837.
Other royal London attractions include St Paul's Cathedral, Clarence House - the official residency of Princes Charles, Harry and William and the Duchess of Cornwall Camilla Parker Bowles - and Kensington Palace.
