Rob‘s sisters Kim and Khloe open up about his relationship with Chyna in a new clip from this week’s episode of Keeping Up With the Kardashians.

“After Rob and Blac Chyna started dating, Rob is now all over social media,” Kim says. “Even though there’s been some drama, if this is what it takes, I don’t care who he’s dating, I’m just happy he’s feeling better about himself.”
