Kelli McCarty

Former Miss USA, Kelli McCarty, who played crazy Beth Wallace on NBC’s “Passions,” and guested on numerous other TV dramas, including “Melrose Place,” “Diagnosis Murder”and “Beverly Hills 90210,” is taking on a new acting challenge.

Porn.

Her first  DVD, “Faithless,” directed by porn legend Paul Thomas, is due out Feb. 4 from Vivid.

“I enjoy acting, and I really like sex,” McCarty said in a Vivid press release, “so this was the perfect opportunity to combine two of my passions. I approached Vivid with the idea of shooting a film with a sexy but interesting storyline, and I was pleasantly surprised with the amount of control I was given throughout the production process.  I am very pleased with the final edit of Faithless, and I just may do another adult film.”

That interesting storyline? Kelli plays a woman whose marriage is falling apart so she seduces her step-daughter’s boyfriend.

Okay, so it’s not “Citizen Kane.”

This venture “marks the first time that a Miss USA, let alone an established TV actress, has made the reverse crossover into adult,” said Vivid co-chairman Steven Hirsch.  “As it turns out, by any standard, Kelli’s performance in Faithless is incredibly erotic.  She smolders sex from every pore of her body.”

“We’ve been credited with spearheading the transition of adult entertainment into the mainstream, but I was still surprised when Kelli approached us,” said Hirsch. “As it turns out, she’s a natural porn star.”

“Faithless” also stars Daisy Marie, Jennifer Dark, Kelly Leigh, Voodoo, James Deen, Steven St. Croix and Herschel Savage.
