Dimension Films have updated their Piranha 3-D viral marketing website, Wild Wild Girls, with nude photos of porn-star-turned-almost-actress Riley Steele in a brilliantly shameless effort to bait chronic masturbators moviegoers to see director Alexandre Aja’s remake of Joe Dante’s 1978 original.

(UPDATE: SEE RILEY MOTORBOAT KELLY BROOK HERE)

Of course, seeing nude pictures of a porn star is like seeing your sister naked—you’ve seen it all before, but it’s nice to know it’s there. But, I digress.

Steele and costar Kelly Brook are  profiled on the site as their party-girl characters Crystal and Danni, respectively. The gorgeous duo also share a nude underwater scene in the flick.

In June of ’09, Riley told AVN:

Kelly Brook is hot. She’s a brunette with natural boobs—she plays Danni. We’re Wild, Wild Girls, but her character is tamer than mine. I’m the crazy girl always out to have fun.

I was nervous when I got this role because I’m not an actress; I’m a porn star. But, luckily, everything that I say is very natural. Crystal is a Girls Gone Wild type of personality. She’s always trying to get girls naked with her and have fun. It’s a very comfortable role for me.

Piranha 3-D stars Elisabeth Shue (Hollow Man), Ving Rhames (Day of the Dead), Christopher Lloyd (Back to the Future), Jerry O’Connell (”Sliders”), Richard Dreyfus (Jaws), Adam Scott (The Return), Dina Meyer (Saw IV), Jessica Szohr (House at the End of the Drive), and Hostel director Eli Roth.

The film arrives in theaters on Aug. 20.
