While the Kardashians and Jenners united for Kim Kardashian and Kanye West's wedding celebration in Italy, one family member decided to fly home early back to Los Angeles without witnessing the ceremony: Kim's brother, Rob Kardashian. 

TMZ caught up with Rob looking visibly upset as he avoided photographer and reporters at LAX airport without saying a word. The site claims that Rob was in tears at the airport while trying to book a last minute flight home from Florence, Italy back to Los Angeles. The reason for his last minute decision? Family drama.

X17 Online further goes on to say that the drama in question happened on Friday when Kim and Rob clashed over his weight and Kim's wedding style. A source tells the site that Kim "wanted the departure from Paris [to Italy] to look like a catwalk, with every member of the Kardashian clan wearing beautiful Valentino couture and looking like a million bucks." This, apparently, started the quarrels between Rob and his family.

The source goes on to say that Rob was "sickened" by the lavish, excessive wealth displayed at the wedding while Kim was upset that Rob hadn't lost any weight for her big weekend.

It's been a rough year for Rob: Back in April, it was speculated that Rob was being treated for depression due to alcohol and weed issues. There were also reports that Rob was going to "fat camp" in order to lose weight for Kim's wedding but he shot down those rumors in a tweet where he stated, "First, I don't believe in rehab or therapy or anything of that sort and second, I'm a grown man and will work on myself when I choose."
