Watch: Is Blac Chyna Hiding Something on Her Phone?

Trouble in paradise?

In this sneak peek clip from Sunday's premiere of Rob & Chyna, Rob Kardashian and Blac Chyna get into a fight over some secret text messages.

"Yo, who's this hitting your phone over and over?" Rob asks his pregnant fiancée while attempting to go through her phone.

"I don't know, what does the name say?" Chyna yells. "And why are you even in my phone?"

"And your password's not the same as it was," Rob adds. "Because maybe last time you went through my phone," she replies. "And why you keep picking up my phone like you don't trust me? That's really whack."

E!

"It's not that it's just I don't get why you even care if I go through your phone," Rob explains.

Chyna explains that maybe she and her mom were having private text conversations that they didn't want anyone to see.

"I don't even understand why Rob would even think that I'm doing anything wrong," Chyna says to the camera. "I'm four months pregnant, I have two businesses that I'm running, I'm with King and I literally don't leave the house so what could I possibly be doing?"

What the clip to see their explosive fight!
