Let the bells ring, for it's Royal Wedding day! The crowds have been building all night long outside Westminster Abbey in anticipation of the most anticipated wedding of the year. As we wait with excitement for the first guests to arrive, the first piece of news to break this morning is that after marriage, Prince William and Kate Middleton will have new titles. They will known as the Duke and Duchess of Cambridge. Interestingly enough Kate will not be known as Princess Catherine Middleton.

We have Catwalk Queen staff on the ground outside of Westminster taking snaps of the colourful crowd, many of whom have dressed up in their regal best. Make sure to stay tuned to the latest coverage of the Royal Wedding, live as it happens. Here are our our top headlines:
