The sleep-deprived Jermaine Paul, still supremely buzzing' over Tuesday's triumph on The Voice (and the accompanying prize $$$ and record deal!) stopped by The Tonight Show Wednesday to chin-wag with Jay Leno.

And that is one formidable chin. HA!

Jermaine is a bundle of emotions, sharing his heightened state along with an adorable Alicia Keys story.

Get infected by Jermaine's joy (above)!
