Tonight The Voice finale kicks off, but fans were given a glimpse into the preparation that goes into it and it's not all work.

Will Contestant Matt McAndrew Of Season 7 Of 'The Voice' Win?

On Sunday, The Voice's YouTube Channel uploaded a video of the finale outtakes, including coaches Adam Levine and Blake Shelton interacting with their remaining contestants in a more fun than serious manner.

Matt McAndrew and Levine converse with each other in Scottish accents and then Levine hurts himself on McAndrew's rings. He says, "Your rings are so hard!" as he shakes his hand around in a bit of pain. He also jokes he'll go to the hospital.

Then, Team Blake's only remaining contestant, Craig Wayne Boyd, is seen candidly talking with Shelton, but he stops himself since he claims he cannot say a certain word, but Shelton proudly states, "Balls! I can say it. The balls. It's got balls so big you gotta walk around with a wheelbarrow in front of you."

Levine is then seen with his wildcard contestant, Damien. Levine sings a little song about Damien being safe. He sings, "Damien. You thought he was not safe, but he is. Yeah!" Levine is then seen dancing around on The Voice stage.

Chris Jamison is then captured with Levine sitting on the side of the stage and Levine is talking about his new hashtag, "#USABaby". Jamison just laughs off the silliness.

Shelton is shown once more with Boyd and they're on stage. Shelton stated, "So this is what it's like to feel," which causes him and Boyd to burst into laughter.

Levine is then shown with his contestants, Jamison and Damien once again so check out the video below to see what other silliness they all get up to.

The Voice season finale kicks off tonight, starting at 8 p.m. ET on NBC.
