The official Twitter accounts for both Kensington Palace (@KensingtonRoyal) and the British Monarchy (@RoyalFamily) stayed quiet on the subject on Wednesday.
However Prince Harry, 31, recently revealed that he regrets "not talking" about the death of his mother for much of his life.

Speaking with former football star Rio Ferdinand, who lost his wife to cancer last year, Harry discussed bereavement at a Kensington Palace barbecue for mental health campaign group Heads Together.
The royal discussed the impact the Princess of Wales' death, when Harry was 12, has had on him when asked by Ferdinand how he coped with the loss.
The prince admitted that it was only three years ago that he began to open up about how he felt about losing his mother, saying he didn't speak about Diana's death "for the first 28 years of my life."

The youngest son of Prince Charles and the late Princess of Wales said he'd come to realise that talking was the key: "It is OK to suffer, but as long as you talk about it. It is not a weakness. Weakness is having a problem and not recognising it and not solving that problem."
He added: "A lot of people think if you've got a job, if you've got financial security, if you've got a family, you've got a house, all that sort of stuff, everyone seems to think that is all you need and you are absolutely fine to deal with stuff."
