VIDEO : Caitlyn Jenner Calls Rob Kardashian 'Stupid' for Posting Private Pics of Blac Chyna

Caitlyn Jenner is the first of the Kardashian-Jenner clan to speak out about younger brother Rob's recent social media tirade against Blac Chyna. The 67-year-old I Am Cait star appeared on Friday's episode of The View, and was hesitant to comment on her stepson's recent behavior. "It?s a tough deal. We?ve had to deal with this, our family," Caitlyn said. "Rob was stupid for doing what he did. He apologized." Caitlyn also revealed that she's "never met Blac Chyna," nor their 7-month-old daughter, Dream.
