Blac Chyna Gets Kendall Jenner’s Sloppy Seconds! Watch The Explosive Feud Unravel

Well this is awkward!

In a sneak peek of Sunday’s Keeping Up With the Kardashians season premiere, Kendall Jenner discovers through social media that her brother Rob Kardashian re-gifted the iPad she gave him to his fiancé, Blac Chyna!

"Rob is dating someone that has kind of had a bad history with my family and he fully re-gifted my gift," Kendall explains in an on-camera interview.

"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 20-year-old model's little sister Kylie, 18, encourages her to call Rob and demand the gift back.

"Yo, um can I have my iPad back?" Kendall asks Rob on the phone. “No, Bible I want my iPad, my pen and my keyboard back."

After Rob tries to play dumb, “what pen?,” Kendall gets angry. "One I'm annoyed, two I'm actually hurt that you re-gifted my f--king gift that I went out of the way to give you!"

But Kardashian has the last word when he tells Jenner she is “hilarious!” “Buy it yourself, you moron!” he concludes... Ouch!
