The couple, who got engaged this April and are expecting their first child together, have signed a deal with E! for six 60-minute episodes of "Rob & Chyna".
Programme's producer, Seacrest, has promised fans to expect the unexpected, reported Female First.
"You can never guess what to expect with that family, but I think it's exciting for them this time. I think because they're expecting. There's so much paparazzi coverage. There's so much talk about them that I think they're excited to show the world what's happening with them," he said.
"I used to run with him on the treadmill. He stopped for a little bit, but he's looking so much better," the producer said.
