Kendall Jenner wants her iPad back!

In a preview for Sunday's season 12 premiere of Keeping Up With the Kardashians, the 20-year-old model is very "annoyed" and "hurt" when sister Kylie Jenner tells her that their brother, Rob Kardashian, gifted his girlfriend (now fiancee) Blac Chyna with an iPad that she gave him.

"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."

"It came with an iPad, a pen and a keyboard and I want it all back," Kendall yells at Rob on speaker phone. "Because if you're not gonna use it, I have someone who actually is really dying for it!"

Rob responds, "That's the first time you've ever got me a gift your entire life!"

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.
