Chrissy Metz stunned the audience when she sang live for the first time on Sunday during the Academy Of Country Music Awards.

Metz took the stage at Las Vegas’ MGM Grand Garden Arena alongside country stars like Carrie Underwood, Mickey Guyton, Lauren Alaina, and Maddie Marlow and Tae Dye (of country duo Maddie & Tae).

Although Metz portrays Kate, an aspiring singer, on “This Is Us,” the ACM Awards marked her live TV debut as a singer – and viewers were pleasantly shocked by her powerful voice.

The women sang "I'm Standing With You," a song off the soundtrack of Metz's upcoming movie "Breakthrough."

The performance was meant to spotlight ACM Lifting Lives, a philanthropic arm of the Academy of Country Music that's "dedicated to improving lives through the power of music," according to the website.

Metz thanked her fellow singers with a post-show Instagram.

"Singing this song with such wonderful women, artists and this amazing choir was truly a gift wrapped in the most special of bows!" she wrote. "To my team who never cease to amaze me, I love you very much! The entire night at @acmawards was inspiring, exciting, emotional and so dang fun!"

She also thanked Diane Warren for writing the song, which Metz called an "anthemic piece of art covered in love and empathy inspired by the true story of @breakthroughmovie."

In the upcoming film, which hits theaters on Wednesday, April 17, Metz plays a devout woman whose adopted son falls through an icy Missouri lake.
