Paul Burrell has claimed he can contact Queen Elizabeth "quicker" than his own agent.
The 59-year-old star worked as a footman for the 91-year-old monarch before later becoming the butler to the late Princess Diana - who died in a car crash in 1997 - and has boasted that he can contact the Queen whenever he chooses, claiming she's easier to get in touch with than the people who work for him.
He said: "I can get a message quicker to the Queen than I can to my agent. And she is not on Facebook and she doesn't have a mobile phone."
Paul made the comments as he prepared to enter the Australian version of popular reality show 'I'm A Celebrity... Get Me Out of Here!', and also discussed the questions he still has surrounding the death of Princess Diana.
He added to Australia's News Corp: "I am mystified. When the accident happened, it took 40 minutes for the ambulance to take her body to the hospital. I went on that journey and it was 10 minutes. So what happened to the other 30 minutes?
"I don't know what happened in Paris because I wasn't there. I know what she told me. I know what she feared. I am not going to tell you dirty laundry secrets, that is not my style.
"I am still loyal and true and Princess Diana's colours are nailed to my mast for the rest of my life. I am going to remind the younger generation of that incredible, unique inspirational human being.
"There is a lot more to say about Princess Diana and the Queen, respectful things."
Despite his ties to the royal family, Paul doesn't think he'll be getting an invite to Prince Harry and Meghan Markle's wedding in May.
He said: "Well, the invitations haven't gone out yet. I used to change their nappies - but what you have to understand is the complexity of all of that world. I don't live in their world anymore and they don't live in mine. It's a very different situation."
