Well, wikipedia says she was born May 7 1968, and appeared in the September 1984 Penthouse.
She started nude modeling in February, turned 16 in May, and made her first adult film in October.
Thing is, I don’t know when the “September 1984” issue of Penthouse actually came out (I often get magazines dated “February” before Christmas, but sometimes get “August” near the end of September), and I don’t know how far in advance those pictures were taken. So I can’t be more exact than “15 or 16” for how old she was.
Her pictorial in Velvet apparently ran while she was still 15, as wikipedia says she dropped out of school because fellow students recognized her from it.
Remember, with the exception of Traci, I Love You, she was under 18 in every single adult film she made, and her adult film career started after being the centerflod in the best-selling issue of Penthouse ever. Since she made adult films for roughly 20 months, she couldn’t have been 17 in those photos.
