It appears that Rob Kardashian's relationship with his fiancee Blac Chyna is unraveling at the seams. According to TMZ, the couple has been fighting for months amidst their new reality show "Rob & Chyna" and Kardashian's weight gain, depression, and belief that Chyna is "going to leave him for a rapper."

"You'd rather date a rapper than a fat Armenian," he reportedly told Chyna.

The couple reportedly broke up earlier this week, and while they are officially together, it doesn't look promising. Kardashian's family is apparently worried for his life.

Chyna had a brief fling with Future last fall and is the mother of the child of Tyga, who dates Kardashian's half-sister Kylie Jenner. Chyna is currently 33 weeks pregnant with Kardashian's kid.
