Rob Kardashian and his family are in a fight once again because of his fiancée Blac Chyna.

The “Rob and Chyna” star was not happy that his sisters arranged a baby shower for his unborn child but did not invite Chyna for the celebration. To avenge his lady love, Kardashian tweeted his youngest sister Kylie Jenner’s number.

Members of the Kardashian-Jenner family have yet to react to what Rob has done. Chyna has not addressed the issue either, although she did say that she was having a baby shower on Sunday on Snapchat. Even those involved in the issue have kept mum, Chyna’s mother, Tokyo Toni, has given her two cents about what happened.

In a Periscope session, Toni weighed in on the situation, saying she understands where the Kardashian-Jenner sisters are coming from. She said that she knows they were only trying to celebrate their brother and his baby, and she saw nothing wrong with that. She also said that she doesn’t mind that Chyna was not invited to the party because it wasn’t thrown for her but for the baby.

There are rumors that the issues the couple is dealing with have taken a toll on their relationship. Some say that Rob and Chyna have already broken up, but a source reportedly told People that the two are still together, though they’re in a “very rough patch.”

“It doesn’t bode well for their relationship, especially considering the baby is coming so soon,” the source added. “They’re not broken up, but it’s not a healthy relationship at all.”

Prior to the issue between Rob and his sisters, he and Chyna also reportedly fought over The Game’s song, wherein he mentioned that he and Chyna had sexual relations. Rob was reportedly caught off-guard, and it shook their relationship.

The two have yet to say a word about the status of their relationship. Meanwhile, fans of the couple can continue following their lives on “Rob and Chyna,” Sundays, 9 p.m. on E!
