Oh, Blake Shelton, you smoothie! Country star Shelton serenades Hoda Kotb on the fourth hour of 'Today' (weekdays, 7AM ET on NBC) with a rendition of "Who Are You When I'm Not Looking" by Joe Nichols.

As Shelton works his way through the love song, the lyrics get increasingly more intimate. Then, after singing a line about a bubble bath, he says, "This is getting kind of awkward."

Clearly enjoying the attention, Kotb urges the singer to go on. "I love it! Go! Go!" she said.
