Prince William hilariously caught his wife, Kate Middleton, flirting with another man on the phone. But the incident isn’t concerning for the royal couple.

Four years after the couple tied the knot, Prince William and Middleton tried to raise money for ICAP during their charity day. The Duke and Duchess of Cambridge competed against each other in trying to solicit the most donations, and they contacted individuals on the phone.

But it didn’t take long for the second in line to the throne to realize what the future Queen had been doing. In order to win over her husband, Middleton seemingly flirted with a broker and Prince William was quick to call her attention.

“Catherine, I think you can stop flirting with him now,” Prince William told his wife. And everyone in the room burst out in laughter.

Meanwhile, Prince William knows a thing or two about flirting because he has been spotted in a compromising situation at least once in his life. Two years ago, he appeared to be flirting with an Australian model while Middleton was in London.

Prince William is spotted gyrating with the model, and he also grabbed her cowboy hat before putting it over his head. At one point, the Duke of Cambridge also wrapped his arms around the model.

A clubgoer said that she was surprised to see Prince William dancing with the model that she had to do a double-take to confirm that it was actually him.

“He was dancing so wildly that I did a double-take when I first saw him and thought it must be a lookalike. But before long everyone realized they really were partying with Prince William,” the onlooker told The Sun.

And royal expert Katie Nicholl said that it will be safe to assume that Middleton won’t be happy to know about her husband’s late-night escapades.

Just recently, Prince William was also accused of flirting with Middleton’s friend, Rose Hanbury. This is reportedly the reason why the Duchess of Cambridge cut ties with her.
