The Celebrity Big Brother house is to be transformed into a palace this week as royal guest Paul Burrell joins the contestants. Paul's visit to the house marks the start of a new task which is sure to send sparks flying. According to OK Online, some of the UK housemates will take on the roles of King, Queen, Prince, Princess, Duke and Duchess. Paul pictured with Princess Diana in 1984 It's thought that the US contestants will have to wait on them as part of the royal task. Paul, who is joining the show as a guest rather than the contestant, is a little nervous about the idea. "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." Paul, former butler to princess Diana, isn't about to let the nerves get to him though, saying: "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." It's believed Paul will enter the show tonight and it's definitely going to be an interesting few days as this task plays out...
