Rob Kardashian and Blac Chyna are "living separately" until their baby is born

A source said: "They are living separately right now until the baby is born because they don't want the fighting to affect the baby.

"They think it is a healthier way to live until the baby is born. He is living in Calabasas and she is in Tarzana. It's just temporary and because they are living apart, the fighting has gotten less."

The couple - who got engaged in April after four months of dating - were said to have not spoken for "months" and as a result of their current relationship status, Rob's sisters threw them separate baby showers, but he decided not to go to his because it was being filmed.

The sock designer, who wasn't said to have been informed of the plan, got "really upset" that his famous family wouldn't let Chyna attend the event without him, resulting in him giving out his half-sister Kylie Jenner's number during a rant on Twitter.

The source added to Us Weekly magazine: "Here's what happened: Kim threw the shower. Kylie [was] the one that Rob called and told he wouldn't go to the shower, because she mentioned it was being filmed.

"He [then] got really upset and told her he wasn't going, but that Chyna still wanted to go. Chyna was all dressed up and ready to go, [but] Kylie then told him that Chyna wasn't invited if he wasn't going to be there.

"She said it was his shower and Chyna could come if they were together

- but if he was going to screw them by not going, then Chyna couldn't come. That's when Rob exploded. It caused a huge fight between Rob and Chyna too, so that's when Rob went off on Kylie on Twitter."

However, Rob and Chyna - who also has three-year-old son King Cairo with ex-boyfriend Tyga - are still thought to be an item, and his family are "confident that they will get through it and patch things up".

Another source told the publication: "Rob and Chyna are not really broken up, but they are not in a good place right now.

"Filming the show has been a lot of stress on their relationship. Add to that Chyna's pregnancy and the fact that Rob and his moods go so up and down.

"Rob really loves Chyna."
