The newest trailer for “Rob and Chyna,” E!'s reality series about Rob Kardashian and Blac Chyna, starts out with the two in happier times. They talk about their excitement over the birth of their baby. In one part of the clip, Chyna's son with rapper Tyga, King, also makes an appearance. Kardashian also reunites with his sister Kourtney's ex-boyfriend, Scott Disick. Disick comments on how long it has been since Rob went out.

Things take a turn south fast, though. Rob and Chyna, while lovey-dovey most of the time, have their fair share of arguments and squabbles.

In one sequence, Chyna questions why Rob keeps checking her phone. Another part of the clip shows Chyna asking why Rob continues to text other women. Rob apologizes by giving Chyna flowers but she's not having it. Rob tears up.

The two later discusses Rob's depression, and Rob's other sister, Kim, makes an appearance as a mediator of some sort. Kardashian-Jenner matriarch Kris Jenner also checks in on Rob and encourages him.

In the clip, it looks like Rob's family has finally grown to accept his relationship with Chyna. The romance between the two is quite complicated, considering how the father of Chyna's son is now dating Rob's youngest sister, Kylie Jenner.

In an interview with People, Chyna admitted that things were not good when they started out. The entrepreneur-turned-reality-star said she understood that Rob's family was being protective of him, especially since he was going through a rough time, so they were skeptical about their relationship and her intentions at first. The Lashed owner is now happy to say that things are better between her and Rob's family.

Chyna added that while they're not at a level where she and Rob will have dinner together with Tyga and Kylie, she is comfortable with having her son around the “Keeping Up With the Kardashians” star.

Will the tension between her and Kylie in the beginning of her relationship with Rob be featured on the show? Viewers will find out when “Rob and Chyna” airs on Sept. 11 at 9 p.m. on E!
