Kim Kardashian and Kanye West have hired a "royal wedding coach" to teach them etiquette.
The couple are preparing to marry next month in France, and the reality TV star, who is famously fascinated by the nuptials between Prince William and Duchess Catherine in 2010, wants their big day to be as "regal" as possible.
A source told UK's Grazia magazine: "Kim and Kanye want their day to be as regal as possible and are studying Prince William and Kate Middleton's wedding for inspiration.
"The coach will apparently spend a week with Kim, Kanye, and the rest of the Kardashian clan in LA, giving them lessons tailored to their 'royal' day.
"They will also be taught about contemporary etiquette and manners carried out by the modern royal family, as well as putting a British touch to their day with all the formal protocol."
And the couple, who have 10-month-old daughter North together, will be issuing guidelines to their guests on appropriate behaviour at the wedding.
The source added: "Their coach has come up with a strict guide for guests, including how to hold a champagne glass.
"They will also be told not to address service staff. Kim and Kanye want this to be as formal as possible."
