Kim Kardashian and Khloe Kardashian are revealing what they really think about Rob Kardashian's relationship with Blac Chyna!
On this Sunday's Keeping Up With the Kardashians, Kim and Khloe are spending time together when the start talking about how Rob's new relationship has changed him.
"Question," Khloe says to Kim in the clip above. "Like don't we kind of think it's a miracle that Rob, who doesn't even show up to Christmas for the past three years, literally he wouldn't leave his room, but the fact that now he's created a Snapchat, the fact that now he wants to be so public blows my mind."
"She gave him confidence, more power to her," Kim says. "After Rob and Blac Chyna started dating, Rob is now like all over social media and like out and about. He hasn't been like this in so long that even though there's been some drama, if this is what it takes then I don't care who he's dating I'm just so happy that he's feeling better about himself."
Khloe then says, "If some p--sy is getting him to remove his braces and shave his beard and work out..."
"My thing is, do what you want, do what makes you happy...whatever," Kim tells Khloe.
But Kim thinks he should've talked to them, especially Kylie Jenner, about his relationship with Blac Chyna.
"He just has no loyalty," Kim says.
"He has no loyalty," Khloe agrees. "Chyna is Tyga's ex and Kylie's dating Tyga now so it's pretty complicated."
