Another family member has turned against Kim Kardashian!

Breaking Celebrity News can report that while the reality star and her sibling Khloe were busy discovering their roots in Armenia, their big sis Kourtney was halfway around the globe and wanted nothing to do with the trip — all because of Kim.

"Kourtney jokes that there wasn't enough room on the plane for her and Kim's ego, so she had to stay home," a source close to the siblings tells Breaking Celebrity News exclusively.
