Florence is starting to look a lot like Calabasas ... 'cause all of Kimye's famous friends have touched down in Italy for the wedding that's taking WAY TOO LONG to finally start.
Kim Kardashian and Kanye West's wedding guests made their way out of an airport in Florence Saturday ... including Jonathan Cheban, Tyga and Jaden Smith.
As we previously reported ... the bride and groom took separate private planes to Italy with their respective parties -- while other guests hopped aboard what looks like a charter 737.
