Paul Burrell will be teaching the American housemates how to be good servants to their British rivals, who are set to become members of the reality TV show's Royal Family this week.
Speaking shortly before surprising the contestants, he said: "I'm apprehensive because it's a totally alien experience. I'm taking in a set of skills to educate the housemates. I'm not a real housemate though - I'm there to help so I'm not competing with them.
"I have met some of the world's most important people - Kings and Queens, Presidents and First Ladies, movie stars and The Pope. I wasn't intimidated by them, so I won't be intimidated by the people in the Big Brother House."
Paul, who also previously served as Queen Elizabeth's footman, will assign roles to each of the American housemates before teaching them how to deliver a silver service.
He added: "I'll try to teach them a little of what I know, whether it's service, manners, etiquette or, knowledge from my world that I learnt for many years by working with the Royal Family."
Despite being excited about appearing on the show, Paul doesn't think he will get along well with everyone.
He said: "I know I'm not going to be liked by everyone because no-one is, but I'm not a quitter. I like a challenge. I love people. There are some great characters in this house and there are people who I wouldn't normally meet in my life.
"You won't hear me swear, you won't see me naked, but I'm not shy and I stand up for what I think is right. It is important to have a voice so don't expect me to stand by and say nothing. I can't manage a Royal Household without having an opinion, and you can't be in the Big Brother House without having a strong character."
