In tonight's upcoming episode, the Kardashian clan takes a trip to the Dominican Republic where Kris and her oldest daughter get into a spat over the Kourtney's apparent "commitment issues."
After momager Jenner invites the brunette beauty to come along on a skeet shooting adventure, she declines the offer saying, "I'm pregnant -- what do you want me to do: Zipline through the jungle?"
This response ends up causing quite the firestorm between the mother and daughter as Kris responds, "You are the most non-committal person I've ever met in my life, first, you can't even commit to where you want to go on vacation, then you can't even get on the right flight…your relationship with Scott? It's like, 'I can't decide if I'm going to have another baby and I don't know if I'm going to get married."
Feeling angry about the shot at her relationship Kourtney fires back, saying, "I'm not going to take relationship advice from you, someone who's meeting up with people from your past, It's disrespectful to Bruce."
