Blac Chyna refuses to back down and apologize to Rob Kardashian — and his famous sisters — following the explosive fight that led to her leaving with baby Dream.

“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 close to the engaged couple tells Hollywood Life. “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?”

Of course, Chy isn’t totally innocent in all of this — shortly after her account was hacked, it was revealed that she called her fiancé “fat, lazy, and insecure” and confessed that she was planning to “stack her money” and leave him.

Rob previously apologized to his baby mama, saying, “This weekend I was in an emotional bad place and did some things that embarrassed myself and my family. 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.”

According to the insider, Rob’s apology was more than justified.

“Rob’s family should be bowing down to her for saving their son’s life,” the insider adds. “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.”

As it was previously reported, Kim Kardashian and her sisters are “furious” with both their brother and his wife-to-be following the fallout of the Instagram hack.

“They are all furious with both of them,” a source said at the time. “They hate Chyna more than ever because she is literally destroying everything that they worked so hard to build. They think Chyna is trying to sabotage them intentionally.”
