Jimmy Fallon may be a professional performer, but even the highly musical 'Tonight Show' host is no match for the professional musician skills of 'The Voice' hosts Gwen Stefani and Blake Shelton. The late night host invited the pair on to the show last night for an epic lip sync battle, and things got ugly, quickly.

Fallon's love of music and singing and getting goofy with it is well-documented -- that and his adoration of silly games have fast become hallmarks of his late night show -- so imagine his surprise when Stefani and Shelton so thoroughly smacked him down. You know what this means, Jimmy? You need to work on your dance skills to compete. We have faith in you.
