It's your typical boy-meets-girl story: Mascara-loving musician on the rebound co-hosts erotica festival with newly single hypermammiferous porn queen. Sparks fly.

Dave Navarro, who announced his "amicable separation" from wife Carmen Electra last month, and Jenna Jameson, just separated from husband-cum-porno partner Jay Grdina, are in the early stages of courtship, reports Star.

"It is true that they are dating," Jenna's rep tells the tab, although Dave's flack isn't quite ready to pronounce them a couple, insisting they're "not officially dating."

Still, the "Rock Star: Supernova" judge seemed to be feeling pretty upbeat about life during a show at the Hard Rock in Chicago Monday night, declaring to the crowd (via the New York Daily News), "This is the happiest I've been in three months!"

Dave and Jenna were reportedly introduced by author Neil Strauss, with whom they both collaborated on ultra-personal tomes, and reconnected in June at Erotica L.A., which is, appropriately enough, the "annual festival of sexuality."

Meanwhile, in still more Navarro romance news, another woman has come forward to say she got up close and personal with him before he went public with his Electra split (he's previously been linked to so-called socialite Sarah Howard and aspiring starlet Casey Durkin).

Moniker-challenged actress Jenae Altschwager tells Star she carried on a "passionate," steamy picture-filled flirtation with the rocker, whom she met in Las Vegas in April but decided against taking things too far when she eyeballed one of Navarro's Carmen-centric ink stains.

"His 'CE' tattoo [for Carmen Electra] on his chest was like a blinking light," she reveals to the tab. "Carmen might as well have come out of his chest and said, 'Don't sleep with my husband!'"

Altschwager's admission could make for an uncomfortable time on the set of her forthcoming flick, "Beyond Legend: Johnny Kakota," in which Electra will reportedly appear.

As for the professional bombshell, she was apparently in no mood to deal with David Blaine at a shindig last week in the Hamptons. The Daily News reports Electra acted "uncharacteristically huffy," declining to pose with the much-mocked magician, who was co-hosting the bash.

Asked one guest, "You think she's turned against all men named Dave?"
