Kim Kardashian's highly anticipated wedding to Kanye West in Italy was an exciting time for her whole family, right? Uh, we're not so sure, as word is surfacing that her brother, Rob Kardashian, flew out of Europe just before the wedding. 

Us Weekly reports that Rob was in Paris this week for pre-wedding festivities but flew back to L.A. just before the ceremony. He apparently booked the return flight on the night before the wedding, and sources report that he was in tears while desperately trying to nab a seat on the plane. He arrived in L.A. (as seen in photo at left) just after Kim and Kanye tied the knot in Florence.

So what could have happened to make him miss his sister's wedding? Us Weekly had reported that Rob did not attend pre-wedding events in Paris with his family on May 21 or May 23, although he was spotted in Paris in the afternoon of May 23. 

Clearly, some kind of big argument must have taken place between the family members in order for Rob to miss his own sister's wedding. Rob has yet to tweet about the Kimye wedding this weekend. 

Rob isn't the only person in Kim's life who didn't attend the nuptials. Beyoncé and Jay-Z also skipped the wedding and were instead relaxing in the Hamptons.

Are you surprised that Rob didn't attend the wedding? And what do you think happened? Let us know in the comments!
