Jenna Jameson -- Torn Between Two Lovers?

Jenna Jameson and Ultimate Fighting Champion Tito Ortiz seemed awfully chummy as they partied it up Saturday in Vegas' Hard Rock Hotel.

Last week, the adult film star revealed she was dating Dave Navarro after separating from her husband, who co-starred with her in porn flicks. Navarro recently separated from his wife, Carmen Electra.

So what's the deal, Jenna? You snagged a rocker and a fighter -- ah, the life of a porn queen.
