Jonathan Cheban and Rachel Roy, two of Kim's closest friends, have posted pictures from the airport in Paris and from the plane itself.
"Early morning with the crew.. here we go.. @lala @olivier_rousteing", posted Jonathan with a photo of the trio drinking espressos in the airport, surrounded by fellow travellers and their luggage.
Details of Kim and Kanye's wedding ceremony are being kept firmly under wraps although the party are expected to be heading to Forte di Belvedere near Florence.
Preparations have been underway at the Tuscan venue since Friday when workers were spotted unloading what looked like thousands of white flowers from a large truck.
Aerial shots of the preparations show the seating arrangement and a black grand piano, suggesting that Kim – who will be marrying for the third time – is to walk down the aisle to the sounds of the black and white keys.
Also visible was the table in which the evening meal will be held, plus the area for the disco.
