Jenna Jameson is Losing Weight and Fans ...

Porn queen Jenna Jameson is so stressed out over her bitter divorce that for the first time in her long career, she’s behaving unprofessionally and letting her fans down, sources said.

Jameson, who reportedly underwent a botched and career-threatening vaginoplasty operation, has lost so much weight that she’s almost unrecognizable and was a disappointment to fans at last weekend’s Exxxotica convention in Miami Beach.

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.”

Jameson has said her dramatic weight loss is due to stress from her ongoing divorce from estranged husband** Jay Grdina**.

The buxom blonde also refused interviews with the media - including CNN’s Ander****son Cooper, The Miami Herald and adult supersite XBiz.com.

She left the event early with her martial-artist boyfriend, Tito Ortiz, when she saw that rival porn star Tera Patrick had a longer line of waiting fans than she did.

Meanwhile, add Spike TV and Ortiz’s organization, the Ultimate Fighting Championship, to Jameson’s list of detractors.

The UFC star backed out of a bout with UFC President Dana White two Saturdays ago after Jameson “berated him for not negotiating a lucrative deal for the fight.” Ortiz had signed a contract to fight White for no extra compensation, another source added.

Ortiz’s no-show left the Nevada State Athletic Commission, the UFC and Spike TV reps steaming mad. One fight fan suggested that Jameson was damaging his career and predicted that she’d be to Ortiz what Robin ****Givens was to** Mike Tyson**.

Jameson’s lawyer told Page Six, “Jenna fulfilled every obligation as set forth from Jay ****Handy [the Exxxotica organizer], and he is pleased with her participation and invited her to come back.”

Handy said, “Jenna fulfilled her contract, and Jenna had a classic Jenna fan line - the biggest line, [one] that wrapped around the Convention Hall.”
