Too much to keep up with? Blac Chyna warns Rob Kardashian about spreading himself too thin on Rob & Chyna's Sunday, October 9, episode, as seen in Us Weekly's exclusive sneak peek.

The E! series' preview clip shows Kardashian, 29, telling his pregnant fiancée, 28, that he and a friend have finalized a deal to start a new business venture. However, Chyna — who is expecting the couple's first child, a baby girl, later this year — has her concerns.

"If you feel like you're being rushed into it, I feel like you should wait," she cautions. The Arthur George sock designer replies, "I mean, it's something that we've been planning to do for a long time."

The makeup maven is still unconvinced that her man's priorities are in order. "I just don't want you to put all this stuff on yourself, and then you just be over it," she tells him.

Chyna adds to the camera, "Rob needs to continue working on his health, his fitness, his sock business. And so for him to try to go get a big brand-new house and to start a new business is a little bit bizarre to me."

A previously released clip from the episode showed the pair's difference of opinion over whether the model should move out of the home she currently shares with roommate Paige, as Kardashian wants to buy them a new abode in which he feels more comfortable.

Watch the tense footage above. 

Rob & Chyna airs on E! Sundays at 9 p.m. ET.
