As the wife of the second in the line of succession to the British throne, Kate Middleton will have her own title and it may be a "bittersweet moment" for her husband, Prince William.
Why? She may receive the same title his late mother, Princess Diana, had.
Prince Charles is believed to bestow his Prince of Wales title to Prince William when his accession comes, making Kate the Princess of Wales. If this happens, it may make the Duke of Cambridge emotional.
Camilla Parker-Bowles currently holds the Princess of Wales title, but she does not use it in respect of its previous owner. So, if the Duchess of Cambridge gets this name, a source told Telegraph, via Marie Claire, that it would highly likely "bring up a mix of emotions" for her better half.
