Range Rover Rob Kardashian  reality

We're still shocked that Rob Kardashian skipped out on sister Kim's wedding to Kanye West over the weekend, but he's stepping out like nothing happened!

On Wednesday Rob cruised around town in his white Range Rover, and he looked a bit stressed when he got stuck in traffic, but clearly he isn't that bothered by the media frenzy surrounding his decision to fly home just hours before Kimye tied the knot in Florence, Italy on Saturday.

A source tells X17online that Kim and Rob had a fight last Friday, and it sounds like he had absolutely had it with Kim's crazy demands. "Rob said he was sickened by Kim and Kanye's display of wealth and clothes and beauty and called it 'superficial bullsh*t,'" a source told us. "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. 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."

We're just dying to know whether Rob has chatted with Kim since the incident...
