I don't know exactly how old she would be today but I first saw her back in the late 1990's and she was a preteen model then. Possibly in her late twenties. They're still using those original sets to sell her as a child model and she's not the only one. Many of the preteen models in the sets you're seeing today could actually be over thirty, married with preteen kids of their own. Sorry if I destroyed any fantasies but I think most who've been collecting them as long as I have already know the reality of it. I'd love to know what she's doing now and if she's still modelling.
Unfortunately there is no information as to what age the preteen model, Trixie, is now. She is still working as a preteen model which would put her age at 12 years old or younger. For more information see: http://trixie.artmodeling-studios.com/tour.html#.
