While you may not know from seeing the trailers which instead focus on female co-stars Jessica Alba and Michelle Rodriguez, Lindsay Lohan also has a role in the upcoming Robert Rodriguez-directed flick "Machete." But while they're keeping her role closed off from any of the advertising, according to reports, Lohan's clothes come off for the movie.

While Lohan has posed nude for magazine spreads before, it's the first time she's gone nude on screen. According to reports from attendees of screenings for "Machete," Lohan's barely in the film at all. And when she is, she's baring it all.

In the film, Lohan plays April, which up until now has only been described as a gun-wielding nun. But she gets into much more X-rated, even incestuous territory, including a ménage à trois with her character's mother and star Danny Trejo in a pool. Her character's father even confesses lustful thoughts about his daughter to a priest, played by Cheech Marin.

It seems that Lohan's role in "Machete" may have been preparation for her upcoming film "Inferno," where she's set to play porn legend Linda Lovelace. She's come a long way from "Herbie: Fully Loaded."

So why keep Lohan's, ahem, contributions to the film a secret? Well, Lohan's recent jail and rehab stint may have to do with it, or the fact that the last time she had a hit movie was "Mean Girls."

But the only person really talking about Lohan as an actress these days, is Lohan herself. She recently covered Vanity Fair, where she told the magazine, "I don't care what anyone says. I know that I'm a damn good actress."

Audiences can see Lohan's assets, as an actress of course, when "Machete" hits theaters on Friday.  icelebz
