Katharine McPhee, 36, posted a video with her “Smash” co-star Jeremy Jordan, 35, to Twitter on Wednesday singing “You Matter to Me” from “Waitress,” which they both starred in at different points.

On Saturday, McPhee took to Twitter saying that she had something special in the works and asked her fans to send photos of front-line workers. The images of doctors, nurses and other essential workers are edited into their moving four-minute performance.

McPhee played the role of Jenna in “Waitress” in 2018, while Jordan played Dr. Pomatter the following year.

The video has received praise from fans on the front line as well as many on Twitter.

“I had chills. This is beautiful,” one fan wrote.

“I love this thank you. Been going to work every single day and working extra hours. It’s tiring and a little scary but it’s okay,” wrote another.
