Blac Chyna and Rob Kardashian are putting on a brave face for the cameras when it comes to their relationship, but it sounds like behind-the-scenes, things are rapidly falling apart.
Despite Chyna sharing on Snapchat the other day — shortly after tweeting out Rob's personal number so he'd have to change it and stop "texting b*tches" — that she and Rob are "good," it sounds like the stress of their whirlwind romance and reality show has taken a huge toll on their working relationship as well. 

According to TMZ, E! execs haven't ordered a second season of the couple's hit reality show Rob & Chyna yet, because they can't get the couple to shoot together. Apparently, Rob has gone back to his hermit ways and producers are worried they won't get a full season out of him.

Ironically, their recent drama — plus the coming baby and rocky road to the altar — has already provided all the plotlines season two could hope for, so producers are keen to make it happen. But, regardless of what Rob does, sources say Chyna's future in reality TV is safe: producers think she's "TV gold" and plan to move forward on a show featuring her, with or without her moody fiancé.

Meanwhile, Rob seems to be coming out of the shadows and supporting his woman. See the sweet message he posted about Chyna just yesterday:
