“Rob and Chyna got into a big fight,” Kim Kardashian said. “We’re all worried about Rob.”

Khloé Kardashian proceeds to call her younger brother and explain that his baby mama has been reaching out to his sisters and airing out their dirty laundry.

“She texts all your sisters and said that she’s ready to leave you,” Khloé tells Rob. However, the 30-year-old sock designer’s response was not expected.

“I definitely do love her and want to be with her,” he said, prompting Khloé to ask, “Am I crazy? What does that mean?”

The controversial couple, who just welcomed daughter Dream together five months ago, have been on and off since getting together in 2016.

“This is my favorite picture of Dream and her Mama,” Rob recently captioned a photo of his daughter with the model. “Best time of my life was being in the hospital for days with my babies 🙂 Woot woot.”
