Yeah, Chanel is not a BCC, but she has a lot of the BCC look to her. In person you can really see that she is a BCI.
As for bubbles, I am just gonna go ahead and call her a BCO/BCI cross as that was what she was said to be, and she looks like one. Looking in Vincent Russos book you can see pure bred Argentines that look identical to her, and other ones that have the mottled markings on the head. Most of them in that book though have the same body markings as she does. The Nics on the other had do not look as much like her.
