Blake Shelton was one of the guests on last night's "Tonight Show w/ Jay Leno" & he did not disappoint!  Now I'm usually a hardcore Letterman fan because he's just an all-round better host, but occasionally I'll watch ol' moon-chin if he has a good guest.  Scarlett Johansson, Blake Shelton and musical guest K'naan--I'm watching!  In this short clip of Blake Shelton's appearance, Blake discusses his late night .....drunk tweets, "The Voice", a potential country duet with Christina Aguilera and more... NOTE CONTENT- Some of the tweets read by Leno are a bit vulgar.  Listen/Watch at your own risk.
