No, this is not about Hollywood Stars’ secret Porn pasts. It’s when the celebrities, for better or worse, cross over into the world of Ron Jeremy for some of the more “expereienced” women in the adult entertainment industry. Here are the top ten of note:

That West Coast Choppers’ figurehead Jesse James was once married to tattooed MILF Janine isn’t all that surprising.  They actually look like a natural fit on the surface.  What is surprising is that James left Janine and re-married with Sandra Bullock.  Yeah, Miss Congeniality must be one “Wildcat” in the sack.

Male porn stars are short.  The girls are even shorter, it helps make the “equipment” look bigger.  Sienna West has likely seen a few large specimens of manhood in her illustrious porn career, but for once it must feel nice for her to have one attached to a proportionate figure like 6′10″ New Orleans Hornets’ sharpshooter Peja Stojakovic, and not some 5′4″ beefcake.

The voluptuous Jayden Jaymes is to washed-up alpha males what Alyssa Milano is to washed-up baseball players:  a readily available orifice.  Jaymes has had her share of flings and stints with former UFC champions, greasy guitarists, and a hollering frontman.  Who knows what’s lurking around the corner next for this social diva.

Iconic porn actress and entrepreneur Jenna Jameson may have walked away from the industry that made her a household name, but she hasn’t left the limelight as she still has a penchant for showing up at UFC pay per view events on the arm of husband Tito Ortiz.  Jameson was linked to Jane’s Addiction guitarist and former Red Hot Chili Pepper Dave Navarro, too.  What is it with this guy?

Porn legend Kylie Ireland can recount a detailed affair she had with Michael Jordan before she was “famous” when she was a dancer in Denver.  The busty redhead claims to have worked the NBA’s greatest player of all-time to such an extent that he put on one of the worst performances of his career on the court the next night versus the Nuggets.  Ireland also claims to have climbed into bed with Richard Dreyfuss, that’s kinda gross.

What a great pair these two must have been, he’s “Unbreakable” and the she’s recognized for her ability to “squirt”.  If you don’t know, don’t ask.

Now, it’s been said somewhere that Alfonso Ribeiro has denied having dated the lovely and talented Ms. Brooke, and thus thwarted the risk of jeopardizing that “Carlton” image, and the risk of a few other things.

Chloe Jones claimed to have had a steamy affair with Charlie Sheen.  That was before she was dead, of course.  Sheen claims to have not have had killed her.  It’s more than plausible that this old devil has had it with more than a few adult film stars, so I kinda have a hard time believing he’d go to so much trouble as murdering one.

Jason Hervey, who played Kevin’s older brother “Wayne Arnold” on The Wonder Years and that’s it, married a porn star.  Good for you.  By most accounts, these two were married.  I wonder if Winnie is still hot.

Seinfeld’s first brush with fame came as vocalist for Brooklyn hardcore band Biohazard, then later on Oz.  Until recently he was married to Goddess of Porn Tera Patrick, during which time he performed on-screen with her and dozens of other women of the industry.  Patrick performed almost exclusively with Seinfeld during their marriage.  On top of being partly to blame for whiteboy rap, Seinfeld managed to rob us of this busty queen for nearly six years.  Shame on you.
