I wonder if she does porn? That is not a snide question, rather a serious one based on those pictures and those of her friends.
It wouldn't surprise me, however, she does have a rather interesting job description:
A Woman Owned and Operated Business Specializing in Boudoir, Models Portfolio's, Escort/Adult entertainment add's (sic) and Custom oil and Watercolor paintings. Priviate sessions in the comfort of my El Dorado Hills home. House calls also available.
Also, look at the correspondence between her and "The Same Girl you've always known." I think Shannon loves more than just Jazz.
