Rob Kardashian and Blac Chyna's new reality show, Rob & Chyna, shows the ups and downs of their relationship.
The six-episode docu-series follows the engaged couple as they gear up for the birth of their first child, and while the new promo reveals the love these two have for one another, it also shows how they fight.

"I fell in love with you because I know how good you are and how loyal you are," Rob tells his pregnant fiancee.
In the very next scene, Chyna is seen screaming at the 29-year-old reality star over the phone. "Are you still texting b**ches, yes or no?" she screams. The 28-year-old model is then seen throwing a bouquet of flowers into the pool.

Rob's famous family makes an appearance in the promo, and his sister Khloe Kardashian appears surprised that her once-reclusive brother is so open about his relationship with Chyna. "That Rob wants to be so public, blows my mind," she says.
"I'm trying to get back out to life," Rob adds. "It's a big change."
In another scene, the dad-to-be is seen kissing Chyna's belly. "Are you ready to be a daddy?" she asks. "It's all I've wanted," he responds.
Just this weekend, Chyna shared a video on Snapchat of the baby kicking in her belly. She also flashed her massive engagement ring.
Rob & Chyna premieres on Sunday, Sept. 11, at 9 p.m., only on E!
Earlier this month, ET confirmed that despite reports, Rob was still filming his docu-series. "He is just going through one of his mood swings, which is common for him. But he is still filming," a source close to the reality star said. "He goes through his dark periods. He gets depressed and doesn't want to really do anything, doesn't leave the house. It got better for a bit when he first started dating Chyna, but he's in a rut now. He'll snap out of it.
