you've had probably one of the craziest years of all time.

-It was insane. -I mean, the record was awesome.

You're now a coach on "The Voice."

There's a Vegas residency happening?

-There's a Vegas residency that starts in April.

-How fun is that? -For, basically, four weeks.

Yeah, should be fun.

-What hotel are you going to?

-We're at the Park MGM.

-That's fantastic. -It's pretty amazing.

You know, Gaga's there. Bruno's there, Bruno Mars.

Pretty special company to be in, and we're real excited.

But we did just come off

basically nine months on the road together.

-How did you feel being on the road for that long?

-Well, it's the longest tour we've done.

It was 90-something shows.

And as close as we are -- And we spoke about it last time,

how we kind of fixed our issues in the family

to be able to work together again.

After 90 shows --

[ Laughter ] -Little --

-You get a little crunchy at times.

-Little crispy, there, yeah.

-We just had a little bit of time off,

and we jumped right back in. But it's great.

You know, we've had quite the journey,

and it's really all thanks to our amazing fans.

So thank you.

[ Cheers and applause ]

-Do you hang out -- When you're on tour,

do you hang out with each other when you're not onstage?

Like, it's all day, like, "Hey, what are you guys doing?

I'll meet you there." -Yeah, definitely.

Like for instance, we were just in the U.K. on tour,

and Joe and his father-in-law organized a pub crawl,

which I'd never done before.

So basically we start, you know, going to bars

at like 11:30 A.M. on a Saturday.

And we just jumped around.

By like the seventh bar, we ended up at some Irish pub

where there was a rugby match on. Ireland was playing.

And it got so claustrophobic that I basically had to escape

and just get out of there.

And I wound up at an Indian restaurant by myself.

It was a beautiful day.

And then a few others felt bad and came and joined me.

But in that case, for instance,

the Irish pub, no one knew who we were.

And that was a beautiful thing.

-So Irish rugby fans and Jonas brothers fans --

-Not the same. -Not the same.

-There's no crossover. -Good to know that.

But with all this stuff happening, I got to ask --

New album? Is there gonna be --

-Yeah, a new album is coming.

-Really? Really? [ Cheers and applause ]

-We figured --

We figured, why slow down?

So, after the last album came out,

literally two or three weeks later,

we were with a bunch of our songwriting friends.

We went somewhere to record, to write,

and came out with, you know, a record pretty much done.

So we've put the finishing touches on it now

with our friend Ryan Tedder once again,

who worked with us on "Sucker" and the last record.

-Love Ryan Tedder. -We do, too.

And we're ready to go. We've had the --

The first single's out now, "What a Man." But then --

-"What a Man Gotta Do." It's unbelievable.

It's crushing it. You know me, I'm a big fan.

You crushed at the Grammys. I loved you at the Grammys.

I go, "Dude, these guys know how to do it.

They know how to put on a show." You crushed it.

And then -- -There was a slight hiccup.

-I didn't notice it. I was watching --

-Slight hiccup. -I didn't notice.

-You didn't notice? -No, I didn't notice.

So, I'm going to show the world this.

Apparently, you had food stuck in your teeth.

[ Laughter ]

I didn't see that. I didn't know that at all.

Who -- Who --

It was all over Twitter -- [ Laughter ]

It was all over Twitter.

How did you find out that you had food stuck --

Did no one check? Your brother?

-No one checked my teeth. -Kevin? Joe?

-So, here's the thing

that's really frustrating about this, okay?

Is that, first of all, there was spinach in my teeth

from my breakfast, which I ate hours before.

-Oh, my God. [ Laughter ]

-So the entire day, no one thought to be like,

"Hey, man, there's something back there."

And then the second thing is,

we're doing an interview like two or three weeks ago,

and the guys are talking casually

about how, like, "Ah, you know, the bummer for Nick

is that we checked each other's teeth before we went onstage."

And I sat there going, "Excuse me?"

-"You guys do that, and you leave me out of it?"

-They left me out of it. And, you know, my manager was there

sitting when I came back offstage,

and we were really excited

'cause the performance went pretty well.

And it was like our Grammy moment, our return.

And I was so amped, and I was like,

"What'd you think?" And he's like --

[ Laughter ]

"Well, just don't check --"

And I went to my phone, and he's like,

"You had a little something in your teeth."

And the first message on my phone was from Adam Levine.

He's like, "Nice performance.

You had a little schmutz in your teeth."

-Oh, no. Oh, my God. [ Laughter ]

And you're like, "I'm so happy! I had a great gig!

I just played my heart out."

-But, you know, it just goes to show you

that you can be performing on the Grammys and be nominated

and still have spinach in your teeth.

-There you go. That's exactly right.
