Maybe it seems mean to ask if Kim Kardashian will invite her own brother to her wedding to Kanye West, but as any avid viewer knows, Rob Kardashian has a bad track record of attending family gatherings.

Let’s recap: Rob passed on the family vacation to the Greek isles — which looked fantabulous. He also sat out the equally extravagant Kardashian-Jenner vacay to Thailand, a trip so magical it appears to have mended the holes in Kris and Bruce’s marriage.

Both times, Rob decided to pass on the (we’re guessing) free plane ticket and, unfortunately, it always seemed to do with how the 27-year-old feels about his weight. As he said to stepbrother Brody about the Greek trip, “I’m so insecure with my weight I don’t want to go anywhere.”

So does that hard and fast rule also apply to your older sister’s wedding? Thankfully, no! An insider tells People that Rob “wouldn't miss this for the world.”

“Sure he’s missed some family vacations, too, but he won’t miss his sister’s wedding,” the source adds.

Also reportedly planning to attend: KourtneyKhloe (sans rumored boyfriend French Montana), Kendall, and Kylie. We’re also expecting Kris, Bruce, and Scott and the kids, Penelope and Mason, to make an appearance.

Though it may seem like half the guest list has a last name starting with a “k” or a “j” this won’t be an exclusively family affair. Kim’s bud Jonathan Cheban and fellow fashionista Brittny Gastineau are on the list as well as La La Anthony, Joyce Bonelli, and Scheppy. But Beyoncé and Jay Z? Yeah, not so much.
