All senior British royals are very much popular today. While Camilla, the Duchess of Cornwall, and Meghan Markle are fairly well-known among the public, as well as Princess Diana, it is Kate Middleton who reportedly tops the list.

It is not surprising why they all differ in their respective ratings. Besides, they all have different characters and personalities.

But, amid all the differences, the four female British royals reportedly have one thing in common. As it happens, they all share the same "love" for wine, according to the Daily Express.

For Kate Middleton, sources revealed that she, alongside her husband, loves to have a nice glass of wine during night time. Before going to bed, or after having a long day, it is said that she fixes herself a glass of wine to "unwind."

Although it does not hurt her healthy lifestyle, some reports said that this is the one "vice" that Kate Middleton has. In the end, though, she always reportedly ensures to follow her healthy Dukan diet.

Similar to the Duchess, her mothers-in-law, the late Princess Diana and Camilla, the Duchess of Cornwall, are also revealed to have the same love for wines. In the case of Prince Charles' second wife, sources reportedly shared that she "grew up" drinking the beverage like the way "they do in France."

Royal expert, Gordon Rayner reportedly shared that the Duchess of Cornwall even brings her own "booze" during her travels with Prince Charles. The expert, who attended over 20 royal engagements also said that the Cornwall couple always brings their own beverage to "avoid" health concerns.

On the other hand, it is said that Princess Diana was not much of a "drinker." However, she reportedly preferred "dry white wine," especially during her discrete night outs from the palace.

Actress Cleo Rocos went on to assert that she used to have drinks with the late Princess. She reportedly revealed that they had peach Bellinis once with Kenny and Freddie Mercury in Bombay Brasserie.

For Kate Middleton's sister-in-law, Meghan Markle, the former actress has repeatedly shared her love for wine. Her favorite, Tignanello, even became the inspiration of her now-defunct lifestyle blog, The Tig, according to Buzzfeed.

Alongside her preferred brand, the Duchess of Sussex also reportedly loves either a glass of "full red" or a "crisp white." She even told in an interview before that she would always choose wine over any "chocolatey dessert."
