Prince Harry once reportedly cancelled his birthday plans over a Kate Middleton 'issue'.
The Duke of Sussex was planning a huge birthday bash when he turned 30 in 2014.
But his plans were cancelled at the last minute due to his sister-in-law Catherine, the Princess of Wales.
Back then, Harry was still a working member of the Royal Family and had close relationships with both Prince William and his wife Kate.
In the lead-up to his 30th birthday, William and Kate had hoped to plan an intimate family birthday dinner for Harry at Kensington Palace.
The guest list was likely to have included his royal cousins Princesses Beatrice, Princess Eugenie and Zara Tindall, along with close friends.
