Caitlyn Jenner has referred to Rob Kardashian as "stupid" after he posted revenge porn pictures of Blac Chyna.
In an interview with The View, Jenner lambasted her ex-stepson for what he did to Chyna despite having never met the former exotic dancer.
"Rob was stupid for doing that and he kind of apologised," Caitlyn said.
"I really have not had much of a relation- I've never met Blac Chyna. I've never met the kid. Rob, I haven't really had a serious conversation with in years. So I've kind of been out of that scene so I really can't comment on what's going on there."
