‘Rob & Chyna’ premieres Sunday, September 11

Luther Vandross was outed as gay after his death.

Rob & Chyna is set to premiere on Sunday, September 11, and if the promo is anything to go by, we can expect the show to be full of ups and downs.

“I fell in love with you because I know how good you are and how loyal you are,” Rob Kardashian tells Blac Chyna in the promo.

The happy scene fades to a less-than-happy one, though, as Chyna throws flowers into the pool and screams at him, saying, “Are you still texting b—–s, yes or no?”

The fight could be what kicked of Kardashian’s decision to remove all evidence of their relationship on social media, even going so far as to unfollow his fiance.

But by the end of the promo, the two seem to be getting along much better, as Kardashian kisses Chyna’s baby bump, and she asks if he’s ready for fatherhood.

“That’s what I always wanted,” he says.

Rob & Chyna premieres on Sunday, September 11, at 9 p.m.
