Kim, Kourtney and Khloe have made legal moves to block Blac Chyna from using the Kardashian name.
Blac Chyna, real name Angela Renee White, attempted to trademark the name Anglea Renee Kardashian, and the Kardashian sister's legal team are opposing the request.
Chyna is engaged to Rob Kardashian and recently gave birth to their daughter Dream Renee Kardashian.
"The Kardashians, like Angela and my other clients are very protective of our marks, I think for us this is going to be a clear case win, because it’s actually her name, it’s not a poaching," Blac's lawyer told People.
According to documents, the Kardashians will “suffer damage including irreparable injury to their reputation and goodwill” if Chyna uses the name.
They also say that the mum-of-two is “deliberately seeking to profit from the goodwill and popularity” by changing her name.
However, the model's lawyer hopes that the suit is a "misunderstanding," as once Rob and Chyna's wedding is over Chyna will legally be known as Angela Renee Kardashian.
"I’m going to zealously represent my client in a trademark we legally filed and a name that we feel like we own and need to protect,” the lawyer added.
Here's to hoping it's all a big mix up.
