According to the Sydney Morning Herald, Prince Harry will inherit £10 million ($17.7m) from his mother's estate when he turns 30 on September 15.

"His older brother Prince William also received a large inheritance from the trust fund when he turned 30 in 2012, although Harry is believed to be receiving more, thanks to interest gained since William's inheritance," the publication writes.

Prince William and Prince Harry are also set to inherit their late mother Princess Diana's wedding dress, arguably one of the most famous wedding dresses in modern history. The white wedding dress was made with silk, taffeta, and lace, featured a 7.5 meter train and was embroidered with 10,000 pearls. Since her death the gown has been in the possession of Diana's brother, Charles Spencer.

Kate Middleton, the Duchess of Cambridge, will be organizing Prince Harry's 30th birthday party. The Mirror reported the party will have a nightclub theme, including dancers and a cocktail bar. Instead of presents, Prince Harry is asking friends and family  for donations to his charity, Walking With the Wounded.

"Kate and Wills want to make it a special night as Harry moves into a new stage of his life," a source told The Mirror.

We hope Kate Middleton invited Prince Harry's new girlfriend and former Miss Edinburgh, Camilla Thurlow!
