Rob Kardashian Cries, Calls Kim "The Most Selfish Person"

As a mother of six, Kris Jenner has a lot of Kardashians (and Jenners) to keep up with, but according to her daughters Khloe and Kourtney -- and son Rob -- Kim is always on top of her mind as her "favorite daughter."

Attending a family therapy session on Sunday's Keeping Up With the Kardashians, Khloe, 28, Kourtney, 33, and Rob, 25, took Jenner, 56, to task for favoring Kim, 31. "Right now, there's some issues between us," Rob admitted when urging his family to attend therapy with Dr. Nicki Monti.

Most of the brood was on board, but convincing Kim to go was a different story. "Therapy's not for me. I'm a very logical person so if I'm acting crazy, I know why," Kim said begrudgingly after being dragged along. "I don't really want to talk to a stranger about my family problems."

In the end, it was Kim who was targeted by her siblings in the first of a two-part episode. "Kim is the most selfish person and doesn't want to ever include me," Rob admitted, after getting into a blowout fight with his sister, accusing her of hampering and interfering with his career. (He later walked out of the session in tears when given his chance to confront Kim following their spat.)

Jenner told the group she doesn't "mean any harm" by favoring Kim, but Khloe and Kourtney felt otherwise, and told their mother as much during the explosive therapy session.

"I don't know why my mom finds it a shock to think she favors Kim," Khloe said. "We're not just my mom's clients, we're her children!"
