>>> meantime, it's a big day on nbc's hit singing competition "the voice." the show goes live tonight, but first, carson sat down with his friends, the four superstar judges to give you a look at what makes their relationship so special.
>> week after week, you watch them as they coach their artists.
>> give me more, give me more, give me more.
>> and feel their pain when they have to send them home.
>> i hate every freaking second of this because my heart's breaking.
>> but when they're not spinning around in those chairs, i get to see another side of "voice" coaches adam levine --
>> adam levine from los angeles , california.
>> usher raymond .
>> blake shelton .
>> you nailed it.
>> and shakira .
>> my hips don't lie.
>> who has a 1-year-old son milan.
>> let's show america our real faces. how about you, shakira ? we've seen milan. been great for me, because my kid's come to the set. i feel like i've got romper room coming on. is it hard to be away from him?
>> it's so hard. that's the only downside of doing "the voice," the times that i've had to leave him back home. but his dad is such a good dad. he's so devoted, so dedicated.
>> your son knows you as a singer. i'm now a full-time coach. i got my son auditioning at home. he's like dad, i want to audition for "the voice."
>> adam, shakira , usher, and blake don't just work together on the set of "the voice." on this night, the four superstar recording artist , who are able to sell out huge arenas almost anywhere in the world, play together at a small club in los angeles .
>> i like the intimacy. it feels good. there goes my baby
>> there's something more intimidating about playing to a small, intimate room. because it's right there and there's people right there, the p.a. is smaller. your mistakes are that much more under the microscope.
>> people, they feel like they know you from watching "the voice." give them one thing about yourself that they may not know about you from watching the show.
>> i think people know a lot about me, but maybe the fact that to me the number one priority in my life is my family, my parents, my baby. yeah, my life at home, i love making music and i hope that i can continue making music for a long time, but if i had to choose one day, it's very clear to me what i want and prefer in my life. but you went away how dare you
>> i would take this opportunity to say, to clear the air, you may pick up a magazine or a tabloid any day of the week that will say something about, you know, my relationship with miranda, it's in turmoil, divorce. and the truth is i've never felt a stronger bond with -- not only with her, but with any other human being in my life. i mean, miranda and i have -- she's my life. ever get over you
>> this year, it's been really one of my hardest years. i lost my grandmother. my son was diagnosed being a type one diabetic. it has definitely been a difficult one for me, man. sometimes y'all look at me and we're off camera and i'm looking online, looking at numbers and trying to make sure that he's eating -- it's crazy.
>> for shakira , for usher, for cee lo , soon to be pharell, anyone who's been a part of this show, we all respect and love each other as people first and foremost. putting that out into the world seems like a really nice thing for a television show . at the end of the day , i will always be able to do this with these guys.
>> for "today," carson daly , nbc news, los angeles .
>> i like that group.
>> you're heading out to do something with "the voice", right?
>> lester, erica, they're all out there, so we'll do another thing that we'll have on "weekend today."
>> are you going to sing?
>> i will not sing, i will not do anything.
>> their green room makes our green room look like a closet.
>> but how does their orange room look?
>> a lot of pressure sitting
