Kim Kardashian and Kanye West are spending £200,000 ($391,075) on a temporary balcony at their wedding venue.
The couple - who have 10-month-old daughter North together - are expected to tie the knot at France's Chateau Louis XIV next month and are keen to replicate the first public kiss between Prince William and Duchess Catherine after they married three years ago, so will have the outdoor gallery constructed to embrace on outside in front of fans.
A source said: "Architects have quoted £200,000 ($391,075) to build a temporary balcony.
"Kim has fallen in love with the place."
Meanwhile, Kanye has been planning further celebrations, including the wedding rehearsal dinner and cocktails the night before their nuptials, and is in negotiations to exclusively hire both the Eiffel Tower's restaurants, 58 Tour Eiffel and Le Jules Verne, as well its conference room.
And when it comes to drinks, the rapper has ordered £18,000 ($35,196) bottles of bespoke vintage champagne, £15,000 ($29,330) bottles of pinot noir red wine and even a Hennessey Beaute du Siecle cognac, which, at £120,000 ($234,645) per bottle, is the most expensive in the world.
The source added:" They want to give their guests a real taste of Paris. Kanye is also in talks to hold a spectacular fireworks display to rival the lightshow at the London Olympics."
Kim will wear three dresses over the course of their wedding celebrations and has had her final fittings.
The source told Britain's Grazia magazine: "Kim had final fittings, including a dress Kanye has been overseeing the design of at Givenchy."
