Will Rob Kardashian's Weight Gain Keep Him From Attending Kim And Kanye's Wedding?

Rob Kardashian's weight gain could keep him from attending Kim Kardashian and Kanye West's upcoming wedding.

Rob is reportedly so "down in the dumps" about his current appearance that he's willing to skip what is being referred to as the "wedding of the year."

In addition to being self-conscious about his size, Rob also feels that he is the black sheep of the family, and despite his closeness to Kanye, he has no desire to attend the Paris wedding.

"Rob is upset about his changing shape and truly feels like the black sheep of the family," a source told Radar Online on March 11.

In recent years, Rob and Kim haven't been all that close and according to the Radar source, Kim thinks Rob is a "total slacker" which is extremely hurtful to Rob.

Another thing that hasn't sat well with Rob is Khloe's recent divorce filing from Lamar Odom.

"Khloe's divorce to Lamar has also been hard on Rob because they had been like blood brothers," said the insider. "Rob would proudly tell anyone that Lamar was the brother he always wanted. It's hard growing up in a family with five sisters and being the only male. His voice was rarely heard."

On Sunday's episode of Keeping Up With The Kardashians, Rob was seen in an out-of-character moment after being reduced to tears over the thought of being seen without a shirt on. After the tears began to flow, Rob explained, "I don't even want to sit down because of how fat I am. I don't know what to do." 

Kim and Kanye are set to tie the knot on May 24.
