Road Less Traveled, which is currently in production in Knoxville, Tennessee, is based on Alaina's new single of the same name.
Alaina portrays a bride-to-be struggling to organise a wedding as her songwriting career takes off in Los Angeles.
"I am so excited to be doing a movie," Alaina said. "This is a whole new world for me. I'm learning so much every day. We have such an awesome cast and crew and I can't wait for everyone to see this new side of me."
