Meghan Markle's nickname for the Queen revealed

The Duchess of Sussex and the Queen of England looked relaxed and happy on their first official engagement

Duchess Meghan and Queen Elizabeth attended their first event together: the official opening of the Mersey Gateway Bridge, in Cheshire on the 14th of June 2018.

The two Royal women took the Queen's private train to Cheshire, and the Duchess greeted Queen Elizabeth formally, addressing her as 'Your Majesty' and dropping a reverent courtesy, reported Daily Mail.

The Duchess and the Queen looked relaxed and happy, smiling broadly and clearly enjoying each other's company.

Ingrid Seward, the editor at Majesty magazine, a publication that specializes in following the Royals, said that in a less formal setting, Duchess Meghan may come to use a different form of address with the Queen.

'They were very relaxed. At one point they were giggling like teenagers together. The Queen looked delighted to be with her."

Seward, who has published several books on Britain's Royal family, namely The Palace in 2008, Queen Elizabeth II: The Diamond Celebration in 2012, and Diana: The Woman Inside in 2017.

Seward revealed that Prince Harry's mother, Princess Diana, used a sweet nickname for Her Majesty. The Queen is addressed as 'Ma'am' which Princess Diana shortened to Mama.

As they become closer, Duchess Meghan may well follow her deceased mother-in-law's example. Judi James, a body language expert expressed the opinion that the Queen appeared 'completely confident' in the Duchess' ability to handle the pressure of a public engagement.

James noted that they were relaxed and friendly, whispering and giggling together like best friends. The Duchess of Cambridge had been married for ten months before she participated in a formal event representing the Royal family.

The Duchess of Sussex has been married less than a month, which seems to reveal the QUeen's confidence in the ex-actress' ability to handle the public.

Duchess Meghan wore an elegant in cream dress with a cape-like cowled shoulder detail by Givenchy. As a particular mark of the Queen's favor, the Duchess wore a pair of delicate pearl earrings, a gift from her Majesty.
