Reality star Rob Kardashian is having doubts about his relationship with Blac Chyna based on her past. Chyna's past boyfriends include rappers like Tyga and Future and Rob is apparently not a fan.

TMZ reports that they have sources close to the couple who say Rob and Chyna have been fighting more than ever based on her past relationships with rappers. Chyna is apparently not allowed to listen to certain rappers' music when Rob is around.

Chyna, born Angela Renée White, has a son, King Cairo, with her former boyfriend Tyga. T-Raww and Chyna had a messy breakup after he left her for Rob's younger sister, Kylie Jenner. After Tyga and Chyna's breakup, she was briefly linked to Atlanta phenom Future. Chyna got a tattoo of his stage name on her hand and appeared in his "Rich $ex" music video last year.

To the surprise of many, Rob and Chyna began dating, getting engaged in April of last year. By May, Chyna announced she was pregnant with Rob's first child.

When The Game dropped a new track titled "92 Bars" last week in which he claimed he and Chyna also slept together back in the day, it apparently caused a rift between Rob and Chyna even more. TMZ reported that the parents-to-be had a blowup argument because Rob wasn’t aware that Game and Chyna had knocked boots.

With Chyna's public dating history skewing mainly towards rappers, could you blame Rob for suspecting history to repeat itself?
