The 30-year-old is seen setting up a new DASH store in New York City with her older sister Kourtney in their new show Kourtney and Kim Take New York.
In a clip of a new episode set to air, ET reveals how the star is upset when her younger sister Khloe arrives at the store and pairs up with Kourtney before they disappear off.
Kim is heard saying: 'The fact that Kourtney and I have been working on this store by ourselves and then Khloe just waltzes in and they go leave without me as if I'm not even a part of it, really hurts my feelings.
'It's really hurting my feelings that the two of them are completely ignoring me on our DASH opening. We should be so excited that we did this together.'
