As Kim Kardashian and Kanye West are still struggling to fix their problems after West's mental breakdown, Kardashian's family has another drama to watch: The conflict between Rob Kardashian and his partner Blac Chyna despite the fact the couple has just had a baby girl named Dream.

According to a source talking to PEOPLE, the 29-year-old new father is always finding ways to start fighting with Chyna. The source also added that he can't control himself and never trusts his baby's mother.

Kim's younger brother always ruins everything when he is with Chyna. Even he fights over unnecessary things. In addition, Kardashian suspects that Chyna only uses their relationship for fame and money, no matter how much Chyna loves him.

Another source also told that Kardashian often cries missing his baby, but can't control his temper with the mother. The relationship is getting worse, even though the couple is quite happy to see people are looking forward to seeing the next episode of Rob-Chyna reality show. Even they promoted the baby's special edition on social media after the turmoil.

Previously on Saturday, Blac Chyna's Instagram account was hacked. Even Tyga's ex-wife claimed Rob Kardashian was involved.

The hacker posed as Chyna, announced that she ended her relationship with Rob and left the baby without letting him know. "I am no longer with Rob" as the hacker wrote.

The hacker then threatened to reveal alleged conversation between Chyna and other men using Kardashian's name. However, the conversation itself didn't indicate Chyna's infidelity. Later Chyna confirmed the messages revealed by the hacker were true, even her fiance played a role in her "hack".

However, despite her worsening relationship, Blac Chyna will make a paid appearance in Las Vegas on January 7, 2017, TMZ wrote. Chyna uses her name as she is still battling over trademarking her married name.

Will the year of 2017 have a better impact on their relationship? That's what viewers are hoping.
