Paul O'Grady, who enjoyed close friendship with Camilla, gave Meghan Markle some important pointers on royal life, saying that the Queen was "easy to get on with" and "likes a good laugh".
The comedian, who died on Wednesday at the age of 67, had reportedly given a blunt warning to the former Suits star before she married Prince Harry in 2018.
Paul, who had a very close relationship with the royal family, gave tips on how to avoid 'riling' the late Queen and warned Meghan about using too many 'non-UK words'.
More importantly, he gave Meghan some tips on what to avoid so that she didn't "rile" her grandmother-in-law. His main advice to the former Hollywood star was to "be totally honest with the Queen" as she is a "straight-talking" person.
The iconic TV and radio star said that he advised Meghan that it could "cause a divide" if she used too many "non-UK words" and that she should "try to avoid too many Americanisms".
Telling TV Times what he advised, he explained: "Always remember to say 'lavatory', not 'bathroom', otherwise you will really rile her!"
Opening up on his bond with the Queen Consort, he told MailOnline: "Camilla's a really funny woman. You can have a great laugh with her and you don't feel like you're on ceremony. I always get a big hug and kiss from her, too, which always shocks everybody."
