DRAMA! Rob Kardashian Left Before Kim Kardashian Wedding In Tears!

Rob Kardashian left Florence, Italy BEFORE his sister Kim got married to Kanye West … and we’re told it’s because some major family drama went down.

Rob booked a flight from Florence to L.A late last night in a hurry … and we’re told he was in tears while desperately trying to secure a seat.

It’s unclear what caused the Kardashian family beef — but it had to be bad — considering he missed out on not only his sisters wedding … but one of the biggest celebrity events of the year.- Tmz
