Blac Chyna is having a tough time getting in with her future in-laws Kourtney Kardashian, Kim Kardashian and Khloé Kardashian — especially when it comes to her utilizing the famous last name.

The four are at odds since the sisters filed court docs to block Chyna from trademarking her soon-to-be name, Angela Renee Kardashian — and a new report claims this really upsets her.

“Chyna is really heartbroken over this whole name feud. She thinks it’s just sad that the Kardashian family can’t stop thinking for themselves and just accept her as one of them," a source tells Hollywood Life. "Her and Rob [Kardashian] are practically married and she’s the mother of his child — why can’t they accept that? She thinks they are total fakes, pretending to welcome her into the family. It was all bulls–t. ”

The model and business owner was hoping to use the name for advertising and entertainment services, including appearances, hosting and social media. Kourtney, Kim and Khloé feel her doing this will cause them to "suffer damage including irreparable injury to their reputation and goodwill."

They also accused Chy of "deliberately seeking to profit from the goodwill and popularity" off their last name.

The mother-of-two had a rough introduction to her man's family because of her long-standing feud with Kylie Jenner, who is dating Chy's ex-fiancé and first baby daddy, Tyga. She and Rob got engaged in April after a whirlwind romance and welcomed their first child together last month — a baby daughter named Dream.
