Rob Kardashian and Blac Chyna's relationship isn't all it seems to be.

In Touch has exclusively learned the couple is putting on an act in order to profit from their successful reality series, Rob & Chyna — and to hide the public from their "messy" and "twisted" relationship.

"Rob had agreed to have a fake relationship with Chyna because his momager, Kris Jenner, got E! to pay him over $2 million to do a show," a source close to the Kardashians revealed.

But Rob now "completely regrets" his decision and is currently turning down any media opportunities that would otherwise help promote the series. Unfortunately, the soon-to-be dad is unwilling to come clean about the "staged" relationship, "It would be too humiliating. The lie has gotten so out of control, there's no turning back."

Chyna, who is pregnant with Rob's baby, doesn't mind going along with the charade, "She wants to make millions from endorsement deals. She's desperate to be as famous as Kardashians."
