Kardashian, 33, married Kanye West in May at Forte di Belvedere in Florence, Italy a day after the couple held a rehearsal dinner at the Palace of Versailles in France.
"We tried to trick everyone, it got leaked and that kinda sucked because we really wanted to surprise everyone and tell them that they'd all been fooled and it's really in a different country," Kardashian said after Kimmel noted that she had revealed on the show that the wedding would take place in France.
In the end, the reality star said a few people were still surprised because of all the conflicting reports put out by the media. Kardashian added that she and West wanted to have the rehearsal dinner and the nuptials in two different locations because the couple wanted their friends to go "on a love journey with" them.
"We fell in love in Paris and then I got pregnant with our daughter in Florence," Kardashian said. "So we kinda wanted to share our love story."
Asked if all of the party attendees "behaved themselves" at the two-day event, Kardashian took a second before revealing that "the night before at Versailles Khloe drank a little too much." The following day, the bride's younger sister was still asleep as she was getting her makeup done for the wedding.
"I was praying she'll get up in time to walk down the aisle," Kardashian said.
