VIDEO : Blac Chyna And Rob Kardashian Purge Themselves From Instagram

Reality star and social media personality Rob Kardashian and fiancee Blac Chyna have deleted images of themselves from Instagram.

Fans of the couple will just have to wait and tune-in to "Rob & Chyna," the duo's new reality spin-off, debuting later this year on E!
