The #worldsmosttalkedaboutcouple was seen arriving at the Palace of Versailles on Friday evening to join their closest friends and family for a pre-wedding dinner before the two make it official.
The 33-year-old E! reality star was dressed in a cleavage-baring white gown while her soon-to-be hubby was seen in a tan-colored suit.
Planning for the pre-wedding celebration began early on Friday afternoon, with countless staff setting up the ornate floral arrangements and other decorations.
An eyewitness tells us that lanterns were set up on the black and white marble courtyard outside of the palace's entrance as well as a giant arch that was erected in the main garden.
Horses with yellow feathered plumes greeted cars as they drove onto the grounds as well as three Baroque drummers wearing costumes reminiscent of the 18th century time period.
Women in wigs who were dressed to the nines in their Marie Antoinette-inspired getups were also seen making their way onto the premises.
In keeping with the French theme, multiple tiered cakes decorated with white and silver macaroons were taken into the palace.
Guests were said to have dined on wild salmon and rice along with a massive salad buffet.
Meanwhile, the floral arrangements for the decadent event were downright stunning.
Pink peonies, white and red roses and snapdragons were all featured throughout the rooms where the dinner took place.
Orange and lemon trees were also specially delivered to the space to provide extra greenery at the scene.
And to top things off, a source tells E! News that fireworks went off for guests to enjoy at the end of the evening.
Earlier in the day, several members of the Kardashian family as well as the engaged duo enjoyed a private brunch at Valentino Garavani's Château de Wideville.
Sounds like a day that friends, family, and Kimye will never forget!
