Blac Chyna and Rob Kardashian will reportedly continue to live separately once their daughter is born.
The turbulent couple - who are engaged to be married but regularly have blazing rows - are set to welcome their first child into the world any day now but, despite the impending arrival, they have no plans to move in together as the 28-year-old model, who also has four-year-old son King Cairo with her ex-boyfriend Tyga, wants a healthy environment for her newborn.
A source told 'Entertainment Tonight': "Rob and Chyna are going to keep their separate houses, even after their daughter is born.
"Rob can be a very hard person to live with. Chyna wants a healthy environment for both her children. If there is any chance of not having that, she will make sure to avoid it at all costs."
The 29-year-old sock designer - who was once a recluse - sunk into deep depression two years ago and, although his relationship with Chyna has improved his outlook on life, his mood swings are still unpredictable and hard to manage.
The source explained: "No one ever knows what kind of Rob they are going to get. He has his good days and he has his bad ones. There are days he responds to texts, days he doesn't."
However, his famous family - including his mother Kris Jenner and sisters Kim Kardashian West, Kourtney Kardashian and Khloe Kardashian - rely on Chyna to keep them in the loop.
The insider said: "Chyna is the one who gives the Kardashian family updates on the pregnancy, baby and relationship.
"Chyna became the person who kept the family in the loop since Rob will go silent for weeks on end.
"She knows that Rob sticks to himself at times, so she has taken on the role of making sure he stays close to the family.
"All the sisters, along with [Rob's mother] Kris [Jenner], love Chyna. They are so thankful that she is in Rob's life."
Rob moved back to his home in Calabasas, California, in September after he had a series of rows with Chyna and she chucked him out of her mansion in Tarzana, California.
He told his sister Kourtney Kardashian's ex-partner Scott Disick at the time: "This cycle of me being kicked out the house has happened several times. 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."
