Rob admits that he's having doubts about living with Chyna. "This cycle of me being kicked out the house has happened several times," he shares. "And usually I go right back, but I'm sick of it. So, I'm going to stay at my house in Calabasas for a bit."
Scott, who has three children with Kourtney, attempts to comfort Rob, quipping, "Dude, you're telling me my own life."
"I know it feels like you're not wanted there, but obviously you just got into a fight," Scott adds, in all seriousness. "It happens, and by the way, she's hormonal, she's pregnant. If you weren't to get kicked out, that would be weird."
On Thursday night, Rob once again deleted all of his Instagram posts while Chyna shared more images of her growing baby bump on Snapchat. The 28-year-old model -- who has a 3-year-old son, King, with Kylie Jenner's boyfriend Tyga -- posed in a bandeau bra and short shorts in front of a fancy sports car.
A source close to Rob spoke to ET last month after reports surfaced that he had stopped filming Rob & Chyna. "He is just going through one of his mood swings, which is common for him," the source said at the time. "But he is still filming."
