My babies 😩❤

A post shared by Blac Chyna (@blacchyna) on

The model and reality star has been proudly showing off her two little ones on social media, and has even created an Instagram account for her daughter where she regularly posts photos and videos of the newborn.

The happy post comes just weeks after a dramatic turn for the engaged couple. In the midst of Christmas, the mom-of-two left Rob, took the children, and moved out of their home. The 29-year-old Keeping Up With the Kardashians star later took to social media to share the details about their reported split and admitted fault.

“This weekend I was in an emotionally bad place and did some things that embarrassed myself and my family," he said. "I apologize and I’m seeking help to deal with my flaws/issues. Please pray for me and I’m sorry [Chyna]. You are a great mother to our child and I love you.”

Though the pair reunited shortly after, the drama did cause a rift in the family throughout the holidays, causing strain between Blac and Rob's sisters. An insider reveals, however, that Blac has refused to apologize for the incident, no matter the reaction from the family.

“Chyna thinks Rob and his family have a lot of nerve if they think she needs to apologize for anything that she’s done in this relationship,” an insider said. “What should she be sorry for? Getting Rob out of his cave and bringing him into the light? Giving him a daughter? Helping him lose weight? Getting him a reality show?”

“Rob’s family should be bowing down to her for saving their son’s life,” the source added. “Rob’s the one who admitted to having issues, and has since gotten [help] from Chyna. She’s so proud of their shared accomplishments, and thinks her behavior and attitude are completely fine. She’s not changing or apologizing.”

Since the drama, the pair has allegedly been trying to give little Dream another sibling.

“She’s told friends she always wanted to have two Kardashian babies,” an insider tells In Touch. “She and Rob break up, move out, get back together and have amazing make-up sex. Chyna could easily be pregnant again already.”
