Rob however proved his love for her and drove to Texas to pick her up, a source told E!
"Officers made contact with the subject on the plane who was identified as Angela Renee White", the police report read.
"The family is in a bind trying to be supportive of Rob's life while being sensitive of Kylie's relationship with Tyga", the source continues, noting that Kylie feels as though Rob "stabbed her in the back".
The mother of one shares a son with Kardashian's sister Kylie Jenner's boyfriend Tyga, and was once close friends with Kim Kardashian West.
"This is not about Kylie for Rob though. For him this is about the whole family and his way at getting back at them".
There was a period when former teen star Amanda Bynes was trying to emulate Chyna's look, reportedly telling In Touch magazine that she got cheek piercings so she would resemble Chyna.
Meanwhile, the model has been released from jail following her arrest for "public intoxication" and "possession of a controlled substance" after boarding a flight from Austin-Bergstrom International Airport here.
