They have been married nearly eight years already, and royal experts believe the key to Prince William and Kate Middleton’s seemingly blissful marriage is the fact that the two are truly a perfect match for one another.

On a recent episode of the podcast The Windsors, royal expert Victoria Arbiter discussed the Duke and Duchess of Cambridge’s relationship and revealed that she thinks the couple’s marriage works so well because the pair are a perfect match for another when it comes to their shared interests and hobbies.

“They are interested in the same things in the way, I suppose, Charles and Camilla on paper seemed a perfect match,” she said. “William and Kate are a perfect match. They love the same things, they love sports, they are both very competitive, they play tennis—they just work. And they have worked since the beginning.”

The couple famously met as students at the University of St. Andrews and even endured a split in 2007 before later reuniting and eventually becoming engaged in 2010. They then married in 2011 and have since welcomed three children—Prince George, Princess Charlotte and Prince Louis together.

Of course, while the couple seems to be happy, it hasn’t stopped them from being the subject of several speculative stories regarding their future. The couple, who will become King and Queen of England someday, have often been the subject of several rumors that they would become parents to a fourth child this year, and betting odds have been very high with the suggestion that the pair will make an announcement regarding a fourth pregnancy before 2019 comes to a close.

The possibility that Middleton would want to have a fourth child has been debated however because she has suffered from hyperemesis gravidarum, a severe form of morning sickness, during her other three pregnancies. It’s unclear if the Duchess would be willing to risk having that condition again in order to welcome a fourth child.

Baby rumors are not the only story the couple has been the subject of either, as several tabloids have tried to claim that Queen Elizabeth was actually bypassing her true heir, William’s father Prince Charles, in order to make William and Kate king and queen earlier as well. Those reports have all been proven to be untrue.
