It’s safe to say that season 12 of Keeping Up With the Kardashians might be the most interesting yet. During a sneak peek of Sunday’s premiere episode, Kendall Jenner cusses out her half-brother Rob Kardashian after she learns that he regifted her present to his fiancée, Blac Chyna.

"Rob is dating someone that has kind of had a bad history with my family, and he fully regifted my gift," the emerging supermodel tells the camera, before phoning Kardashian to yell at him. "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."

The gift in question is an iPad, which Jenner gave to Kardashian for Christmas.

"Yo, can I have my iPad back? No, Bible, I want my iPad, my pen and my keyboard back,” the 20-year-old tells her older brother over the phone, before shouting, “You regifted my f--king gift that I went out of the way to give you!"

Tensions within the family have since cooled off. As previously reported, Rob’s famous family has come around to his engagement to Chyna.

“Rob’s rehabilitation continues to astound the family,” a source previously told Us of the formerly reclusive reality star. “They really believe that it’s all Chyna who is responsible for bringing him back.”

Watch the sneak peek above. Keeping Up With the Kardashians season 12 airs on E! Sunday, May 1, at 9 p.m. ET.
