Katherine Heigl is busting out her singing skills and we love it!

In an exclusive clip from the upcoming film Jackie & Ryan, Heigl takes the stage – and yes, she is actually singing!

“I was pretty anxious when I had to get up on stage and there was a crowd of extras there to be a part of the scene,” Heigl told ET. “I think I probably turned beet red and my hands were shaking, but then after you do several takes and several angles, I started to feel more and more comfortable.”

In the film, Heigl plays Jackie, a former singer at a crossroads in her marriage who has a chance encounter with Ryan (Ben Barnes) as he performs on the streets of Utah.

After a sudden car accident propels them together, Ryan and Jackie find the strength and music they need in each other.

Jackie & Ryan arrives in theaters on July 3.
