"They're all gonna laugh at you!"

Those words were burned into pop culture history thanks to Piper Laurie's performance as Carrie White's unhinged mother in "Carrie" ... and may have been in the back of "Riverdale" star Madchen Amick's mind when she got cast in the CW show's musical interpretation of the film.

When the series returns from its spring break next week, it'll tackle one of the biggest bombs in Broadway history. With Kevin Keller (Casey Cott) at the helm, Cheryl Blossom (Madelaine Petsch) in the title role and Betty (Lili Reinhart), Archie (KJ Apa) and Veronica (Camila Mendes) filling out the cast, viewers are in for on helluva show. And as the musical's sole adult cast member, Amick admits she was "nervous" about the vocal gymnastics that came with playing Margaret White.

"My father was an accomplished musician with a world touring band. I spent my childhood on the road with him. I grew up playing musical instruments. I then married an incredibly talented singer, songwriter, musician husband. We now have two very musically talented children, so long story short, I'm surrounded by music," Amick told TooFab. "But I've never considered myself a singer, so yes, I'm nervous!"

She added that her work in the episode has "definitely taken me out of my comfort zone," but powered through thanks to the help of a "lovely and supportive vocal coach."

Playing Carrie's uber-religious mom also allowed her to step into the shoes of one of her former costars. "Alice Cooper really enjoys getting under Margaret White's skin to deliver a chilling performance," she added. "I personally got a kick out of paying homage to my fellow 'Twin Peaks' legend Piper Laurie."

The actress also teased that the themes of "Carrie" and its music will "creepily coincide" with the storyline of the show.

The "Carrie" musical episode of "Riverdale" airs April 18th on The CW.
