Last night on The Voice, Blake Shelton and Adam Levine were up to usual shenanigans! The two were in the middle of taking jabs at each other when Blake threatened to tweet Adam's personal phone number. So Adam called Blake's bluff and you got it, Blake did it! Soon after Adam's phone started ringing.
The tweets then began to flow of all of the followers trying to call Adam. Both Adam and Blake did answer a few phone calls.

Do I think it was Adam's real phone number, no! But it did make for a good stunt.
