First, he wasn't invited to Kim Kardashian's big proposal, now he's not even going to walk her down the aisle?!
Hm, maybe the reality starlet is being superstitious since her last marriage did fail and Bruce Jenner was the man who walked her down the aisle!
That's probably not the reason, but an insider spilled:
“Kim is planning on walking down the aisle alone because it’s her third wedding and being 33, she feels silly having someone give her away.
It would make no sense for her devoted stepdad — who walked her down the aisle when she married Kris Humphries — to perform the ritual again, since he recently split from Kris.”
