Older sister Khloe Kardashian, 31, was said to be very angry with Rob, 29, and said to have felt completely betrayed when she discovered that her sibling wanted to get married to Blac immediately. Previously, when Khloe found out that Rob was in a relationship with Chyna, she was also furious at him.

She allegedly could not believe that Rob did not inform the Kardashians beforehand. Khloe promised not to acknowledge their plans of getting married and will not send Rob any well wishes.

US Magazine also reveals that the family matriarch Kris Jenner was not too happy about Rob’s huge life decision. An insider shared that Kris was not keen about the news. The whole family is said to be discussing the matter and angry about the engagement. They may make united and address the problem together, although it could lead to consequences.

As for Kanye West, the rapper said that he was not invited to the wedding. His wife, Kim, has also not yet commented on the issue.

According to Elite Daily, Adrienne Bailon, Rob’s ex-girlfriend, was more positive about the engagement news. She said that Rob appears happy and said that it was great that he was getting hitched.
