Jenna Jameson: A Very Skinny Curmudgeon

We can barely see the newly skeletal Jenna Jameson.

Reportedly, fans in Miami now wish they never had the chance to at this weekend's Exxxotica film expo.

The porn star, who recently underwent a botched vaginoplasty, let down fans that showed up to get her autograph.

While she didn't get into any breast-related trouble, as fellow adult movie legend Ron Jeremy did recently, word has it that Jenna was bitten by the jealousy bug.

"She was contractually supposed to show up for a total of six hours in two days, yet arrived late both days and blew off the event 45 minutes early on the second day of her appearance," one source told the New York Post.

She also allegedly refused to answer fans' questions about her Nicole Richie-like weight or her surgery.

Then, she supposedly left early when she saw that fellow porn actress Tera Patrick had a longer line of fans and admirers than she did.

For their part, event organizers say they were happy with her participation. Exxxotica's Jay Handy said: "Jenna fulfilled her contract, and Jenna had a classic Jenna fan line - the biggest line, that wrapped around the Convention Hall."

Jameson blames her extreme weight loss on stress from her ongoing divorce from estranged husband Jay Grdina.

We'll let you know what Keira Knightley blames her weight loss on if she ever talks to us again.
