Kirstin Maldonado and two members of her popular cappella group have frozen their way into our hearts.

The half Mexican-American singer, Scott Hoying and Mitch Grassi, all members of NBC’s The Sing-Off-winning quintet Pentatonix, have released an endearing new medley on the web.

Maldonado, Hoying and Grassi joined voices to perform four of the popular songs from Disney‘s new animated hit Frozen: “Do You Want to Build a Snowman?,” “For the First Time in Forever,” “Love Is an Open Door” and “Let It Go.”

Instead of releasing an a cappella medley, the trio sings along to the karaoke tracks from the film while acting out scenes in front of a white curtain at the Endless Noise studio – complete with a blonde wig, snow made out of paper cutouts and lots of tossed pillows and blankets.

Maldonado, who could totally be the voice of Disney’s next princess character, Hoying and Grassi, who sang together in high school before recruiting more members to compete in The Sing-Off’s third season, recorded the video as part of Hoying and Grassi’s online series, Superfruit, which also recently featured singer Tori Kelly.

Bass Avi Kaplan and beatboxer Kevin Olusola don’t appear in this unofficial Pentatonix video, which has already earned nearly 800,000 views on YouTube.
