An interesting sneak peek behind the production of "The Voice USA" has been released.

The clip includes bloopers of coaches doing their thing. The funny video showed how the coaches were acting during taped episodes.

Adam Levine was even caught taking a couple of sandwich bites when he was called out by a producer because he has delayed production with his snack break.

As E! Online noted: "Levine makes his way back to the stage, sandwich in hand, as he gets adorably busted by the other coaches! His face is absolutely priceless when he realizes everyone is waiting on him. And when he tries to hide the sandwich? Just amazing."

Other judges' funny moments were also featured. There was Blake Sheldon trying to ask the other judges what their favorite name for "poop" is.

Pharrell was also caught admitting his shirt was worn inside out. Then, Christina Aguilera was vocalizing and the other judges, Pharrell and Adam, joined in to have a "screaming competition." The judges were trying to outdo each other by being louder than the previous one but, just as suspected, Christina won this one as she stood with the audience cheering for her.

There was even a part when Adam got into a steamy, not serious, argument with Blake. He said that Blake just needs to remind the contestant that they live on the same area and instantly, the contestant would decide to join Blake's team. Christina tried to cool them down and said, "Adam, you've gotta let it go."

Meanwhile, Madonna is set to perform on "The Voice UK," but she has an issue with BBC.

She reportedly requires an extravagant arena which is about 24 ft. by 24 ft. This arena will be a bullring that should be able to house "10 dancers and 12 gospel singers," according to Mirror.

Show's producers are not sure if this could be done since "The Voice UK's" state at Elstress Studios is too small to fit Madonna's demand.

A source told Mirror, "Getting Madonna on 'The Voice' would be a major coup."

"She's not going to do anything by halves. So if the Beeb want her, they're going to have to accommodate her - and her bullring - whether it's in the usual studio or they find something temporary," the source added. "It's got to be a huge spectacle or it won't happen."

"The Voice USA" will be back for its 8^th Season on Feb. 23 at 7 p.m. EST.
