Oh, I'm right there with you buddy, but based on how many folks bought her fucking 'bath water' this is just another wrung on the logical progression ladder for her. Imagine how much she's charging, and the commission she gets off each one?
I don't think she had an actual model made. I think it's just a generic doll that she's put in her makeup and clothes, although she's apparently going to sell or raffle this doll off (of course she is).
There are a few different companies that have made unofficial Belle dolls in the past, and those cost around $1500-2000
