In Netflix's new holiday rom-com "Christmas With You, [1]" Aimee Garcia plays Angelina, a Latin pop star dealing with career burnout who's tasked with writing the next "All I Want For Christmas Is You"-level holiday song. Garcia steps into the role of the singing-dancing extraordinaire so seamlessly that one might assume she's actually a pop star. So, is Aimee Garcia really singing in "Christmas With You"?

The answer is yes, and Garcia, who is not a trained singer — believe it or not — tells POPSUGAR taking on the role of an international pop sensation was "terrifying." While Garcia has some singing experience after recording a song for a season five musical episode of Netflix's "Lucifer," the role of Angelina presented a whole new challenge.

"Netflix had offered me this role in 'Christmas With You' because of the musical episode on 'Lucifer,' but I barely sang and danced [for that]," Garcia says. "And [I] may or may not have taken a shot of tequila in the sound booth. I cannot confirm nor deny." Making matters even more intimidating, Garcia was on a time crunch to nail Angelina's powerhouse vocals. "I only had three days to learn all the songs . . . so when they said, 'You're going to play a professional singer with multiple Grammys and platinum records worldwide,' I had a minor panic attack."

Panic attack number two came when Garcia heard which pop stars the producers behind "Christmas With You" were hoping for Garcia to emulate. "[When I asked], 'What kind of voice are you guys thinking?' And they're like, 'Oh, you know, Mariah Carey [2], Kelly Clarkson [3].' 'Oh, so the best singers of our generation?' I said, 'Not gonna happen in three days.'"

In the end, Garcia let go of the doubts in her head and instead studied pop legends like Madonna [4] and Britney Spears [5], whose legacies helped her reach an encourageing epiphany. "Their performance is undeniable, right? They are pop stars. They are legends," she says. "And I said, 'I'm just going to lead with my strengths of dancing performance and sing from the heart . . . And that's all I can do."

According to her costar Freddie Prinze Jr. [6], who plays Miguel, the widowed music teacher who reignites Angelina's passion for writing, Garcia isn't giving herself enough credit. "Girl, they cut a soundtrack and are releasing it . . . because you killed it so nice," Prinze Jr. says. "They don't do that unless it's good!"
