The Voice introduced its two newest coaches – Pharrell Williams and Gwen Stefani, who teamed up to perform "Hollaback Girl" – on Monday night as the eight remaining artists performed.
Team Adam Levine star Christina Grimmie followed last week's genre-bending Drake cover with another original moment on Lil Wayne's "How to Love."
The audience would not stop cheering. "You should be soaking this up right now," Blake Shelton praised. "You look and sound like a superstar up there."
