The socialite was given a list of strict rules to follow when she met the 83-year-old monarch at the Royal Variety Performance yesterday (07.12.09), and has jokingly claimed the sovereign is very demanding.
Nicole posted a photograph of her instructions on her twitter account, along with the phrase: "Rules for meeting me. That's right, I'm a DIVA with a capital D!!(sic)"
The letter – titled "Etiquette Notes" - depicts the traditional rules people must follow when meeting members of the British family.
It reads: "Please can all artists who are taking part in The Royal Line Up to meet Her Majesty take note of the following:
"One first addresses the Queen as 'Your Majesty'. Please wait before offering your hand. It is not mandatory to curtsey or bow. One does not speak until spoken to. After that, one can address Her Majesty as 'Ma'am' as in jam not 'Mar'am' as in smarm.
"You first address the Duke of Edinburgh (Prince Philip) as 'Your Royal Highness'. After that it is 'Sir'. "
Underneath the picture, the 28-year-old TV star wrote the note: "At royal variety show. Rules for meeting her majesty. God save the queen!"
The Royal Variety Performance is an annual variety show held in the UK, which is attended by members of the British royal family.
It will be aired on British TV channel ITV1 on December 16.
