Just one month after welcoming daughter Dream, Rob Kardashian and Blac Chyna have split.

The 28-year-old beauty's Instagram was hacked, exposing private messages with her friends, attorney and Jaden Smith that allegedly prove she was in the relationship for the wrong reasons.

"Imma give Rob 1 year to get it together. Or I'm gone," she wrote to her best friend Treasure in one of the leaked messages. She goes on to call him "lazy, fat and insecure."

In another, she discusses trademarking the last name Kardashian with her attorney, and reveals her plans to ignore momager Kris Jenner.

"When I get married 7-7-17, I will just trademark it then," the mother-of-two wrote. "I'm not going to ask Kris. Will it be easier when I'm married?"
