Vegas Popular reports that Jenna Jameson’s ex husband, fellow co-star Jay Grdina, is working hard to avoid running into her new boyfriend, Ultimate Fighter Tito Ortiz, at the Adult Video Expo in Vegas. They say both men have hired extra security and obviously don’t want to see each other while they’re at the event. Jenna has a new adult video she’s promoting that she shot with Grdina.

Jenna’s ex, Grdina, is said to now be dating Shanna Moakler, the estranged wife of Travis Barker. I thought that Barker and Moakler were seen making out in public recently but if this is true she seems to be moving on anyway.

But the most intriguing juicy gossip in this strip-off show-all head-to-head combat is the whisper that, since New Years, Jenna’s ex has been out on dates with Travis Barker’s ex, Shanna [Moakler]. (You all remember the divorce-cake she cut-apart last fall at LIGHT nightclub in the Bellagio!) Ah the wicked web that love lets loose.

Jameson recently blasted men in the porn industry for relying on Viagra, saying she’s glad it wasn’t so popular back in her day. “All you have to do is look at their red faces to know they’re taking something so they can perform. It’s disgusting. I’m glad I got out before the heavy pill-popping started.” You can’t blame them, considering they’d have to be superhuman or use lots of editing to go through all that.

Jenna Jameson is looking kind of scary skinny at the AVN Adult Entertainment expo. In some of these pictures she just looks thin, but in others she looks like a stick. Her face seems to be, uh, quite different too.
