Prince William and Kate Middleton may be the picture-perfect royal couple, but despite their strong bond, they are believed to have ‘blistering rows’ now and then, according to Express UK.

According to royal author Robert Jobson, who claims that the Duke of Cambridge has a ‘particularly short fuse’ in private, Kate and William, who have been married for nearly a decade and have three children together, don’t always see eye to eye.

In his book William at 40: The Making of a Modern Monarch, Jobson quoted a source as saying about William: “He can be a bit of a shouter when he loses it.”

The same insider added: “It’s fair to say the Duke and the Duchess give as good as they get if their disagreement results in raised voices. But they know each other so well, it usually blows over quickly – and she is, on the whole, a major calming influence on him.”

Commenting on their upcoming 11th wedding anniversary, Jobson also said: “As the couple approach their wedding anniversary next Friday, friends say the key to the marriage’s success is that it’s an equal partnership – even if that involves the occasional blistering row.”

One friend of the royal couple told Jobson: “They’ve got a solid relationship and she gives him confidence. There is no jealousy, no friction – they are happy for each other’s successes.”
