Blac Cyna and her fiancée, Rob Kardashian, are edging closer to the premiere of their new reality show, Rob & Chyna, and it looks like the drama is not about to be slighted. According to the Daily Mail, in a clip for the show, the model was seen breaking down in tears after having an ugly fight with Rob.

In another scene from the show's trailer, Rob sits beside Chyna while going through her phone.

"Yo, who is hittin' your phone over and over?" he asked as he scrolled through.

Chyna responded, "Why do you wanna keep going through my phone like you don't trust me?"

Rob doesn't seem to be the only with trust issues as Chyna also blew up at him about "b*****s he was still texting."

Take a look at the trailer, below:
