You've never seen Ashley Tisdale quite like this!

Though she's already strayed far from her "High School Musical" roots with racy guest spots on "Sons of Anarchy" and "Young & Hungry," Tisdale's latest role in "Amateur Night" is about as gritty as it gets.

The dark comedy stars Jason Biggs, playing a not-so-together dad-to-be named Guy Carter who takes a job as a driver after his wife, Anne -- played by his real-life spouse, Jenny Mollen -- sees the posting on Craigslist. Turns out, the gig is driving around three foul-mouthed sex workers: Fallon (Tisdale), Nikki (Bria Murphy), and Jaxon (Janet Montgomery).

ET has the exclusive first look at images from the film, some funny but mostly NSFW.

Last month, ET sat down with Tisdale, Murphy, and Montgomery in Los Angeles, where the actresses admitted that they didn't have any qualms about playing prostitutes on the big screen. In fact, Tisdale said she was "ready to jump right in."

"I have to go in and fight for these roles," she explained, noting the perception she gets due to past projects like "HSM." "When they first heard about me coming in, [the directors] were like, 'Yeah, I don't think she's right for this,' and I was like, 'No, no, I want to do this!' And I love Jason Biggs, so I was really excited that I got the chance to do it."

"This is so different from anything anyone's seen me do," she added.

Murphy did admit she was a bit apprehensive at first, but it was mostly due to her father -- yes, that Eddie Murphy.

"I was nervous at first, just because of my dad, specifically," she told ET. "He's been in this world for so long, and I respect him so much, and I was like, 'Oh my god, my dad's gonna see me half-naked and dancing for men!' He saw it, and he was super supportive and really impressed by my performance, so all good there. But at first, it was a little nerve-wracking and watching with him in the room was terrifying. I had my hood up the whole time and my hands over my face and tears in my eyes -- just so nervous!"

"I give her props! My dad is not allowed to see this!" Tisdale quipped after Murphy made her admission.

Montgomery doesn't pretend that she was fully on-board with her itty, bitty costumes, however, especially during one particularly aggressive scene.

"I'm pretty liberal -- I'm an English actress -- but there's some things I'm keeping to myself," she explained, specifically referring to keeping her private parts private. "I had to go into a room with one of the costume guys and one of the costume girls and one of the makeup girls, and they had to superglue me into this costume to keep me in place. As I was there getting my vagina superglued to this white PVC leather body, I thought, 'God, what am I doing with my life?'"

While Tisdale, 31, is excited for people to see her and her fellow fabulous females in these bold roles, she didn't take the part as a means to dismiss her "HSM" roots.

"When you have something that successful that kind of took on a world of its own, you are gonna be known for that character, and it's important as an actress to really challenge yourself and do different things," she said. "I never wanted to neglect my audience, because they're why I'm here today."

"So, I've taken baby steps," she continued, "but over the last three years specifically, I really wanted to do things that scare me and make me come out of my comfort zone, and this one definitely scared me!"
