The pic on the left of Jenna Jameson is from late 2003, and was published in XXX: 30 Porn-Star Portraits, by Timothy Greenfield-Sanders. This pic of Jenna from that collection was on the cover, but she had a few more inside.
The pic on the right was taken this past weekend at LA Erotica '07. Rumor has it she's been cast in Gremlins III: The Girls Take Over.
I guess it's a good thing she has over 100 adult features to her credit at this point. At least we can remember how she looked before her plastic surgery fetish.
