The 28-year-old model attempted to submit a request to trademark her full name - which would only include the famous surname when she marries fiancé Rob Kardashian - earlier this week, but was met with difficulty when the legal representatives for sisters Kim, Kourtney, and Khloé Kardashian filed documents to block her request from going through.
Now, 61-year-old momager Kris has stepped in to cool the feud between the girls, and has reportedly reassured Chyna that it was merely a ''simple mix-up''.
According to TMZ, Kris told Chyna ''there's no beef ... it was a simple mix-up and she's calling off the legal eagles''.
The publication also reports that Kourtney, 37, Kim, 36, and Khloé, 32, have ''reached out'' to their future sister-in-law - who shares newly born daughter Dream Renée Kardashian with 29-year-old Rob - to reassure her that ''their lawyers were following standard operations'' when the documents were filed.
It isn't the first time the feud has been speculated to be a big misunderstanding either, as a source close to the family previously stated the girls' lawyers ''automatically oppose'' anyone who places a trademark request for their name.
The insider claimed: ''Their trademark attorneys automatically oppose anyone trying to trademark 'Kardashian'. I doubt the girls were even aware. Everyone loves each other. It's just business.''
The news comes after Chyna - who also has four-year-old son King Cairo with ex-partner Tyga - was reportedly left ''heartbroken'' by the feud.
A source said: ''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. 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.''
