Rob Kardashian has come a long way since the launch of his sock line.

In a clip for the upcoming new episode of Rob & Chyna, the 29-year-old is seen finalizing his plans for a clothing line with his friend Nick — much to the dismay of his pregnant fiancée, Blac Chyna.

"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," she said.
