"Rob is dating someone that has kind of had a bad history with my family and he fully re-gifted my gift," Kendall explains. "On top of it, it's so annoying to find out through social media because his girlfriend posted it. Like, there's some things that just aren't cool and I don't think this is very cool."
Kendall is so upset with her older brother that she calls to demand that he give back the iPad, and Kylie encourages her to do so, "right now."
Kendall then calls her 29-year-old brother "defensive," to which he replies, "Buy it yourself, you moron!"
While tensions appear to be high between Rob and his sisters in the upcoming KUWTK episode, Kylie and Chyna revealed last week that they are hanging out. "So happy my girls finally got to talk and make peace! #MyFamily #AllLove," Rob Instagrammed on Friday, along with a pic of Kylie and his fiancee.
