A down-on-her-luck porn star has been found living in a massive tunnel that stretches for miles underneath the Las Vegas Strip.

The filthy, gaunt-looking woman — identified in reports as former X-rated actress Jenni Lee — was discovered by a Dutch TV crew while interviewing some of the hundreds of homeless people who camp out in Sin City’s storm drainage system.

Lee, whose real name is Stephanie Sadorra, gives her name as Stephanie and laughs nervously as she tells Ewout Genemans, host of the show “Ewout &…,” that “I used to be in pornography.”

Asked if she was successful in the smut industry, Lee answers, “A little too successful, maybe.”

“I actually got very famous. I should still be top 100 on some, you know, some list somewhere,” she says.

“I used to be so hot.”

Lee — who appears to be missing teeth and picks at her fingers with black-rimmed nails — also says that living in the drainpipe is “not as difficult as you think.”

“Everybody’s really respectful,” she says.

“People down here are good to each other, which I don’t think you find much.”

Lee, 37, was born in Clarksville, Tennessee, and worked as a model and appeared in TV commercials before becoming a stripper and porn actress, according to biographical information posted on the IMDb website.

The Internet Adult Film Database credits her with appearances in 105 films, including “Jenni Lee’s Office Fling,” “Horny Hosts of Heaven” and several installments of the “My Daddy’s Hot Girlfriend” series.

The 5-foot-3-inch, 105-pound performer — who has a sun tattoo above her privates — last worked in front of a camera in 2015, the site says.

Homeless people have been living in the Las Vegas tunnels for years.

Although they provide relief from the scorching desert heat, the tunnels pose a flooding risk during storms that can fill them with more than a foot of water per minute, according to a 2009 report by ABC’s “Nightline.”

“They can be very dangerous,” Matthew O’Brien, author of “Beneath the Neon: Life and Death in the Tunnels of Las Vegas,” told the show.

“A lot of [the dwellers] are really good about communicating with each other about when it’s about to rain, so they can just grab their valuables and get out, and leave everything else behind.”
