We already knew that Dustin (Gaten Matarazzo) from Stranger Thingswas an amazing singer, and it turns out that his costar Millie Bobby Brown has some impressive pipes, too. The 14-year-old actress shared a new video showing her singing a duet with none other than Jacob Sartorius, and it’s guaranteed to put a smile on your face.

Brown starts off the duet, sitting closely to the camera and singing some of the lyrics to Sartorius’ song “Nothin’ With You.” Sartorius can be seen playing an acoustic guitar in the background of the short video clip, which was put through a filter to make it look like vintage, black-and-white video-camera footage.

Sartorius then takes a turn singing a few lines of his own tune while Brown continues to provide backup. Eventually, the two crack up when the 15-year-old singer makes his way up front to mug for the camera. As they start smiling and laughing, the clip cuts off.

This is the first time we’ve seen the talented teenagers singing together, but Brown and Sartorius do make occasional appearances on each other’s Instagram feeds.
