The sisters also addressed the family’s ongoing drama with Rob’s ex-fiancéeBlac Chyna, with whom he shares 2-year-old daughterDream. Chyna, 30,sued Rob and his familyin October 2017, arguing that she suffered “significant damages” after her ex’s social media rampage that summer, in which he shared graphic and expletive-ridden content about her — including three naked photos — whileaccusing her of drug/alcohol abuse and infidelity.

Chyna alleged that the nude photo scandal — along with Kardashian family’s influence — are what gotRob &Chyna, the couple’s E! reality show, axed after one season.

A judge recentlygranted Chyna a trial datein the case, set for Feb. 3, 2020, with pre-trial depositions of Khloé, Kim,KrisandKylie Jennerto take place in the spring of 2019.

OnWWHL, the sisters brushed off the legal battle.

“[We’re] still in a lawsuit,” Kim said. “We don’t know. We don’t care.”

“We just honestly can’t keep up,” added Khloé, who also admitted she was “a million percent sure” Rob and Chyna’s relationship wasn’t going to work out.

A source told PEOPLE earlier this month that Robremains focused on his daughter— and is intentionally choosing to stay out of the spotlight.

“His biggest joy is being a dad to Dream,” the source said. “He’s still seeing his family and spending time with his sisters and mom, but he doesn’t like the social situations or being on camera right now.”

As for his relationship with his ex? According to the insider, the two no longer communicate.

“When it comes to Chyna, he really wants to move on,” the source said. “They don’t have a relationship and deal with Dream through an intermediary.”
