Meghan Markle should seek the advice of Camilla, Duchess of Cornwall if she marries Prince Harry, according to a royal expert.

The 'Suits' actress - who, like Camilla, has been divorced in the past - has been dating the flame-haired royal since mid-2016 and in recent months, speculation has been rife that the duo will soon tie the knot.

But Robert Lacey, historical consultant for the hit Netflix series 'The Crown', believes Meghan could learn a lot from chatting to Camilla about the challenges of joining the royal family.

He told the New York Post newspaper: "Times have changed and the heat is off Meghan. She is a new recruit but, apart from being assigned a lady-in-waiting, it would be demeaning for her to get too much advice from courtiers.

"The best person to give Meghan advice would be her fellow divorcée, Camilla. I wouldn't be surprised if she had taken Meghan aside for a strong gin and tonic and some helpful tips on joining the royal family.

"She's a very funny woman who's had it all thrown at her but survived."

Meghan and the Prince have kept a low profile since they've been dating.

But in an interview conducted earlier this year, the brunette beauty insisted dating royalty hasn't changed her.

Meghan - who was married to film producer Trevor Engelson from 2011 until 2013 - said: "We're two people who are really happy and in love. We were very quietly dating for about six months before it became news, and I was working during that whole time, and the only thing that changed was people's perception.

"Nothing about me changed. I'm still the same person that I am, and I've never defined myself by my relationship."
