This weekend sees the premiere of 'Rob & Chyna' and in a sneak peek, the couple can be seen having an argument over Blac Chyna's text messages. Rob Kardashian begins by asking from another room, "Yo, who's this hitting your phone over and over?" Chyna replies, "I don't know, what does the name say? And why are you even in my phone? And why you keep picking up my phone like you don't trust me? That's really whack."
