Kim K consoles Blac Chyna for the baby after Rob K disappears

Kim Kardashian and Blac Chyna had a heart-to-heart about Rob Kardashian, who disappeared as she told the mother to be to hold on till he "gets it together" for their baby on the way.

The couple reportedly had an explosive argument on a 'Rob and Chyna' episode, which leads to him blocking her number and going radio silent, reports E! Online.

After their fight, the pregnant girlfriend decided to attend his grandmother's birthday in San Diego without Rob and there she learned that the youngest son had also blocked Kris Jenner, Kim Kardashian, Khloe Kardashian and Kourtney Kardashian's numbers.

During the party, Kim and Chyna sat down to talk about Rob.

Chyna explained that she wants to be with Rob but it was "frustrating" because he "really thinks sometimes that I don't love him."

Then 35-year-old Kardashian told Chyna she hoped Rob "gets it together" for their baby that's on the way.

Earlier last month, Chyna had reportedly kicked Rob out of the house after the two decided it would be better for their relationship to live separately.

However, the couple started to discuss moving back in together after sometime.

"I know that me and Rob has been going through a lot of things but I'm actually happy that we're talking about moving back in together," the 28-year-old said then.

"Rob has been working on himself, the baby is on its way and it's exciting to know that we're getting everything together before this baby comes," she delighted in the statement.

Few days later, the couple was seen driving in the car when Rob's french fries accidentally fell on the car floor and the couple got into an explosive argument.

In a clip, the reality star is seen consoling Chyna who fears she would end up a single mother.

"We've all tried to come at him in different ways and with our own personalities and he's not gone for any of it. So it's nothing that any of us have done, it's really within himself. I just hope he gets it together for the baby," Kim said.
