During an appearance on Jimmy Kimmel Live, The Voice judge humbly accepted the honor and gave a pretty funny acceptance speech.
"This is a tremendous honor...unbelievable," he started, speaking at a plastic podium. "A lot of people sort of trivialize this kind of thing, they say it's shallow, it's just a silly media stunt used to sell magazines and perpetuate the image of Hollywood being based on looks...and that's totally true!"
"But, I'm completely cool with that," he concluded.
The rest of his speech was equally funny, as he documented his journey of becoming so "cool, confident and seductive."
