Rob Kardashian and sister Khloe reconciled over baby news

Rob Kardashian and his sister Khloe reportedly ended their estrangement after learning his fiancee Blac Chyna is pregnant.

Editors at Us Weekly report the 29-year-old Arthur George sock designer patched up his differences with his famous family after informing them all one by one that he was to become a first-time father.

The strained relationship between Rob and Khloe is often featured on the family's reality show, Keeping Up With the Kardashians, with a recent episode revealing Khloe wanted her mother Kris Jenner to cut off all financial help to her brother.

However, the siblings have since worked things out, with Khloe sharing a picture of herself holding hands with her little brother on her Snapchat account last week (end01May16).

Now, an insider has revealed the pair reconciled over Rob's surprise baby news.

"Rob and Khloe spoke three weeks ago and they worked things out," the source tells Us Weekly. "The baby brought them together. Rob is having a baby, which is huge and she needed to be there for him. It was the right thing to do."

The formerly reclusive reality star has been dating Blac since January (16), and announced their engagement last month (Apr16). Blac shares three-year-old son King Cairo with former fiance Tyga, who is currently dating Rob's youngest half-sister Kylie Jenner.

The Kardashian-Jenner clan has yet to publicly comment on Blac's pregnancy news, which broke on Friday (06May16), and the model's representative claims she was pressured into making the announcement earlier than intended after the story was leaked to the media.

"She would have preferred to have announced it on Mother's Day (08May16) herself, but her hand was forced," he said. "Allegedly the other half of her family leaked her story so she had to announce it.

"The only people that knew from Chyna's side was myself and Amber (Rose, best friend). Her mother didn't even know. (Chyna's) moment was taken from her, which is really sad... It's the business. There's a TV show to promote."

Despite the setback, Blac is in good spirits and enjoying her pregnancy. "She's very happy and doing great. She hasn't had morning sickness. It's been a very easy pregnancy thus far," her rep said.
