Royal expert says Prince William gave Harry a warning just before his wedding to Meghan.

Understandably, Harry didn't take very well to his older brother's advice and to be fair, that's the case with most siblings. Apparently, William was of the opinion that things were moving very fast between his brother and his wife-to-be Meghan Markle and so, he brought up this with Harry before the wedding. The couple started dating, got engaged and were married within two years so it has been described as somewhat of a whirlwind relationship. Speaking on Channel 5 documentary, royal expert Katie Nicholl said:

"William was quite concerned that the relationship had moved so quickly."

Katie went on to say that although Prince William meant this as "brotherly advice" it only served to "rile" his brother. To be fair, you could see why Harry could see this as interference in his relationship and the timing wasn't exactly perfect either, so close to the wedding itself. According to The Express, Katie believes that things haven't been right between them ever since because Harry felt William was criticising his decision to marry Meghan. For quite some time now, there have been rumours of a feud between Meghan and Kate and indeed distance between Harry and William too. Perhaps this is where it all started? Again, it's all mere speculation and we'll take this with a pinch of salt but as Katie is the Royal Correspondent for Vanity Fair, it is fair to say that she know her stuff when it comes to the family.
