Chrissy Metz Makes Her Singing Debut With Carrie Underwood at the 2019 ACM Awards

The 'This Is Us' actor made her live musical debut at the star-studded show and got some help from country music's biggest stars.

Chrissy Metz made her musical debut at this year's ACM Awards on Sunday, when the This Is Us star took the stage to deliver a stunning performance alongside some of today's most celebrated female country artists.

Metz began her emotional number alone on stage, showing off her range and talent with a performance of "I’m Standing With You," a single from the soundtrack of her upcoming faith-based drama, Breakthrough.

Rocking a gorgeous sapphire gown, Metz looked every bit as regal and elegant as her voice sounded, and was soon joined by Lauren Alaina and Mickey Guyton as well as Madison Marlow and Taylor Dye of Maddie & Tae, who all rocked similar royal-blue ensembles as a symbol of support and unity.

While Metz proved she could hold her own as a singer, the collaboration elevated the beautiful performance to a whole new level that was only heightened when Carrie Underwood stepped out on stage for the song's heartwarming conclusion.

As the number came to an end, Metz had tears in here eyes while basking in the applause and cheers of the impressed crowd.

The wildly talented group of singers stopped to talk with ET's Nancy O'Dell backstage after the performance, and Metz marveled at getting the opportunity to make her singing debut alongside the artists she idolizes.

"It’s super exciting to be with these incredible artists who I am a true fan of," Metz shared, excitedly.

The actress also opened up about how she prepared to take the stage, and admitted that she didn't feel nervous, but instead focused on getting ready mentally and emotionally.

"It’s not about being nervous, it’s just about being centered and being present and grounding yourself," Metz explained.

Earlier in the day, ET spoke with Maddie & Tae prior to the big show, and the pair opened up about what it was like to work with the "incredible" actress and how it felt to be a part of such a monumental performance.
