On Saturday morning, instead of getting ready for Kim Kardashian’s wedding to rapper Kanye West, Rob Kardashian was boarding a flight from Paris to Los Angeles. Initial reports claimed the reality star’s brother was tired of the “superficial bulls---,” but it turns out that was not true.

The 27-year-old allegedly got into a huge fight with Kim, after she was mad that he did not drop any weight in time for her wedding. “Kim was pissed that Rob hadn't made an effort to drop any weight over the past few months,” a source told X17. “Rob basically thinks Kim cares about him only for his appearance and he said he'd 'make life easier' for her and just leave.” In addition, Rob reportedly did not want to be in Paris to celebrate the wedding in any case, believing it was too elaborate. "Rob said he was sickened by Kim and Kanye's display of wealth and clothes and beauty and called it 'superficial bulls---,” the source continued.

However, according to E!, none of this is true. "Kim and Rob did not fight," a source says. "He wanted to be there, but he was feeling so insecure and didn't want anyone to see him heavier like this. Kim and Kanye completely understand. They love Rob and only want him to be healthy and happy."

Another source tells E! News that Rob's "in a really bad place right now" over struggles with his weight.

Earlier this month, Rob began to trend on Twitter due to his weight gain. He had not been seen in public since January, and fans presumed it was because he was in fat camp in an effort to finally lose weight he has steadily gained since last year. He was seen May 19 at LAX heading to Paris for his older sister’s wedding celebrations.

“so I found out I was trending for being fat… thank you all it really made me day [sic],” Rob 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. 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,” he continued, before saying, “I’m aware that I’m fat that de faint a surprise to me lol and my only therapy will be in the gym anyways had to say somethingggggggggg [sic].”

Rob started gaining weight after a bad breakup with singer Rita Ora last year. Rob is not the only Kardashian who has been blasted in the media because of their size. For years, Khloe also faced backlash for years due to her stature and weight. The 5-foot-10-inch reality star has since lost at least 30 pounds by working out and eating healthier.
