Prince Harry and his new wife Meghan, Duchess of Sussex have been nicknamed ‘’Monica and Chandler’ by royal insiders because of the contrast between the LA-born actress’s control-freak personality and the Prince’s easygoing nature.

In the long-running sitcom Friends, romantic opposites Monica Geller and Chandler Bing eventually get together despite the fact that she’s obsessive about every detail and he’s just interested in a quiet life.

According to The Sun, the royal family’s staff have given the couple the affectionate nicknames because Meghan is seen as ‘wearing the trousers’ in their relationship – insisting on skipping the Firms traditional Christmas shoot for example – while her husband goes along with her desires.

Royal fans have also noticed big differences in Harry's appearance since he met Meghan.

The playboy prince slimmed down ahead of the Royal Wedding, and and many believe he might now be following his wife's healthy diet.

Meghan used to blog about her love for food, speaking about how she was vegan in the week but enjoyed her favourite treats at the weekend.

During his tour of Australia and New Zealand he wore an unusual black ring, which experts claim was a health tracker device.

Harry also reportedly quit smoking when he started dating Meghan, giving up his 20-a-day habit.

Sources claim he started smoking at school and then took it up again when he was in the Army.

Last year a source said: "Harry has promised no smoking at all at home. It's not nice for Meghan as a non-smoker.

Keen royal-watchers have also noticed changed in Harry’s dress sense and even his social circle - changes which have been ascribed to his eagerness to please his new wife.

Conversely, though, a new paper by academics Laura Clancy and Hannah Yelin claims that Meghan’s social conscience has been muted by her new family.

Their report says: “While the monarchy appears to be celebrating her diversity and modernising influence, then, this is only permitted within prescribed boundaries.

"Markle’s activist voice has been either silenced or appropriated by the monarchy.

"She has quit her acting career, closed down her popular blog and social media accounts for all her online activity to be ciphered through Kensington Palace.

“Meanwhile, Markle is said to be receiving ‘duchess lessons’ from the Queen’s advisers, to be brought up to speed with protocol and expectations of life with the monarchy.”
