Rob Kardashian's absence from sister Kim's wedding to Kanye West over the weekend has been a major talking point in the days that have since passed, and now a major US gossip outlet claims to have uncovered the real reason he walked out.
The reality star is said to have been taken over by major insecurity over his weight, and refused to pose for any photos - despite support and encouragement from his family members, according to TMZ.

The site reports that the situation escalated more and more as Rob refused to play ball; eventually deciding he'd had enough of the whole thing and opting to fly home to LA, missing the whole ceremony altogether.
The family, including Kim, is thought to be completely "heartbroken" over his decision to leave.
However, nobody from the family has commented themselves.
Kim and Kanye are thought to have jetted off to Cork, Ireland, for a five-day honeymoon away from the public eye.
