Is This the Moment That Led to Rob Kardashian & Blac Chyna’s Epic Blowup?

Check out a new sneak peek of Rob Kardashian and Blac Chyna’s new reality series “Rob & Chyna.”

In the clip, Blac Chyna was seen screaming into a phone, “Are you still texting b**ches?” and throwing flowers into a pool.

Last month, Rob and Chyna sparked rumors they had split when he deleted all the photos of her from his Instagram. At the time, a source told E! News, "Rob and her have been getting into little tiffs and Blac Chyna flipped on Rob. He was so pissed at how she spoke to him, so he deleted everything about her to hurt her.”

Aside from the drama, the teaser also included a sweet moment of Rob kissing Chyna’s growing baby bump and showing excitement over his impending fatherhood.

“Rob & Chyna” premieres on September 11 on E!
