There Goes the Defense? Jenna Jameson "Chillin'" After Passing Drug Test

Former porn star proves she's clean by submitting to tox screen in wake of Tito Ortiz's post-arrest claim that she's addicted to OxyContin

That's one allegation down for the count.

Within hours of his arrest for alleged domestic violence this week, Ultimate Fighting champ Tito Ortiz tearfully stood before the press, denying that he hit Jenna Jameson and announcing instead that the former porn star was a drug addict with a predilection for OxyContin.

Jameson was quick to deny the drug allegation, and today there's proof to back up her squeaky clean claims, according to her lawyer.

"To refute the lurid and unfair allegations of drug use, I had Ms. Jameson register with one of the most prestigious testing centers in Nevada to freeze all scientific evidence on her person," attorney Ronald Richards told E! News.

Translation: She took a drug test. So how'd she do?

Let's just say it's not going to help Ortiz's defense any.

"It unequivocally shows that any statement suggesting drugs were involved with my client are patently false," Richards said.

"She was watched, ID'd and examined. The tox screen was taken under the most stringent conditions," Richards said.

Jameson and Ortiz have not been in communication since the UFC fighter's arrest Monday, and from the look of things, it will stay that way for a while.

Jameson is currently vacationing in Las Vegas with friends, but is holding up well.

"She is fine," Richards said. "She is chillin'."
