Rob Kardashian and Blac Chyna are being hush-hush on the details surrounding the upcoming birth of their baby – for a very big reason.

“Rob is still very excited about the baby,” a source close to Kardashian tells PEOPLE. “When someone asks how Chyna and the baby are doing, he smiles and says, ‘great.’ They won’t share any details. They are saving it for their show. Even when friends ask, they refer to their show and say they will share it all on the show.”

Shortly after announcing their engagement, Kardashian, 29 and Blac Chyna revealed that they were expecting a baby and would be sharing their journey on a new E! reality show called Rob & Chyna.

The couple are excited about their new career, the source says.

“Chyna would never accept money from Rob’s family,” says the source. “She always worked and wants to continue to find ways to make good money. She stopped doing club appearances now, so the money needs to come from somewhere else. Both Rob and Chyna are very excited about their show. They can’t wait to share everything with their fans.”

Though the couple is staying mum on the major details regarding the pregnancy, Chyna, 28, has been sharing fun updates via social media.

“Like no lie, my goal is to gain 100 lbs. this pregnancy,” she previously said in a Snapchat video. “I’mma tear it up, and then I’mma snap back.”

She added that she was “having a really good pregnancy.”

“No morning sickness, no cravings, just baby,” she said.
