Rumours abound that the royal foursome are in the midst of a feud, with a constant stream of reports suggesting that its the two duchesses, Kate and Meghan, who are butting heads in Kensington Palace.
But now a royal source reveals that it is actually Harry and Will that are in the middle of a feud.
A royal commentator has discussed the William and Harry feud - watch the video below for all the details:
According to royal commentator and former Sunday Express editor Martin Townsend, the rumours that Kate Middleton and Meghan Markle are feuding are really just a clever ploy to distract the public from the real feud - between their husbands, Express.co.uk reports.
Speaking to Today, Mr Townsend said: "I think that’s more likely that there’s tension there.
"There was this suggestion that William had had a word with Harry before the wedding to Meghan, saying he didn’t think Meghan was really Princess material. Apparently, that really upset Harry.
"There are stories that have emerged recently about a rift going back many, many years where Harry would behave badly. There was a time when Harry was cautioned by the Police for underage drinking and smoking, and he thought that he was getting all the blame for that whereas William’s behaviour was just as bad.
"William was getting away with it. There are these historic rifts and then there are a few tensions around the whole Harry and Meghan thing."
