You'll Wonder Why Demi Lovato Isn't Nominated For a Grammy After Seeing This Performance

Demi Lovato's voice is indescribable. The singer showed off her best vocals during a performance of her emotional song "Stone Cold" on The Ellen DeGeneres Show on Feb. 10. Her rendition of the piano ballad was so emotional and powerful, the audience was absolutely silent during the entire thing — they were all probably as breathless as we were when we watched this video.

This appearance — where she revealed she wouldn't mind getting an engagement ring from boyfriend Wilmer Valderrama — was just a warmup for Demi's busy week. She'll be performing "Hello" in a tribute to person of the year Lionel Richie at the Grammy Awards at Los Angeles's Staples Center on Feb. 15. We're willing to bet Demi's first-ever performance on the Grammys stage will leave everyone in awe.
