She looks like a Yorkie to me. Georgie has big ears too. I agree 100% with Annabelles_Mom buying a Yorkie from a site like this isn't what your friend should do if she wants to be guaranteed a purebred AKC registerable Yorkie. Me personally I think she is adorable and would be happy to give her a happy home (possibly negotiating a lower price), but I am not as concerned as she may be.
BTW buttercup is definitely a Yorkie and an adorable one too
