It's hard out there for a porn star...

At least it has been lately for porn queen, Jenna Jameson, who is so stressed out these days from a vaginoplasty (OK, that sounds TERRIFYING) and a messy divorce, that she is practically wasting away from worry. And now, the usually professional Jameson recently disappointed her fans at last weekend's Exxxotica convention at Miami Beach, atypical behavior for the woman who usually goes out of her way to keep her fans happy. According to the New York Post:

According to one insider, "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."

The source continued, "When fans openly asked her about her [botched surgery] and why she was so thin, her people cut them off. But she shouldn't be standing in front of an old photo of herself when she's about 40 pounds skinnier than she was."
