The Kardashian-Jenner clan is known to be high on drama, and the days leading up to Kim Kardashian's wedding to fiancé Kanye West was no different. Reportedly, Kim got into a tiff with her brother Rob, and this prompted the latter to skip his sister's wedding.

The two came to blows about Rob's weight gain, which has attracted much media attention off late.

"Kim was bashing Rob about his weight and how he would ruin the pictures that would be taken with the family," a source told HollywoodLife. "It got back to Rob and he called her out."

Reports have it that Rob blasted Kim for being superficial and dissed Kim and West's show of wealth. The incident occurred on Friday, before the wedding guests gathered at designer Valentino's chateau for lunch. X17 reported that Kim wanted the entire clan to look glamorous in beautiful Valentino couture, and Rob was having none of it.

Kim was also unhappy with the fact that Rob had not managed to lose weight before her wedding day.

"Rob said he was sickened by Kim and Kanye's display of wealth and clothes and beauty and called it 'superficial bullsh*t' but Kim was pissed that Rob hadn't made an effort to drop any weight over the past few months. Rob basically thinks Kim cares about him only for his appearance and he said he'd 'make life easier' for her and just leave," a source told X17.

"He just doesn't seem to feel comfortable or happy around his family at all. They're all wrapped up in the same pretty world and he just doesn't fit in."

Rob has been struggling with his weight gain for a while now, and he is said to be deeply depressed about it. Last week, he began trending on Twitter after he was photographed jetting out of LAX for Kim's wedding.

"So i found out i was trending for being fat… thank you all it really made my day,' the Kardashian brother tweeted. 'And to the blogs saying i went to fat camp or rehab LOL then why am i still fat u fools?? y'all must have run out of real news," Rob wrote, adding that he is aware that he is out of shape.

Khloe too lashed out at haters for critiquing someone for their looks and added that negative comments from haters could leave scars for a lifetime. But during Rob's tiff with Kim on Friday, not even Khloe took his side, reports said.

"Why is Rob overweight? Because he is deeply depressed and is in denial about getting help. His family should be very concerned with his well being right now. While they are having the time of their lives, their son, their brother is suffering immensely," added a HollywoodLife source.
