-I loved it. I just like the whole cast.

I love Blake, Kelly.

-They're alright. They're fine. [ Laughter ]

-John Legend. -We love him.

-Yeah. -But here's the thing.

I expected Blake to be the real, you know, tough one.

-The antagonizer. -Yeah.

He's been there forever.

He's ancient. [ Laughter ]

No, he gets a little cranky at times.

But, actually it was John that --

by the midway point of the first day after lunch,

because everything was cool. They were like,

"Man, you're gonna be fine. We're gonna break you in.

It's gonna be a great experience."

And I was thinking, "This is pretty simple."

I thought they were gonna be hazing me kind of, you know,

when I first got there. -Yeah.

-And then John was the one that really surprised me.

-Really?

-He came out and the gloves came off.

[ Laughter ] -Really?

-But he's got a reputation.

He's got the EGOT now. -Of course.

-And apparently he's the sexiest man alive.

-He definitely is, yeah. He's the sexiest man alive.

-He definitely is. -He also has Chrissy Teigen,

who's one of the funniest, sharpest people out there.

You want to have her in your corner.

She writes good jokes.

-So, safe to say, we have a good chemistry together.

It was a lot of fun. -You could tell.

-But it's real. -It is real.

-I mean, you cannot leave yourself open

or they will pounce.

-And your brothers came in to be your mentors, right?

-They did. Yes.

-That's gonna be great.

-They were the cheapest I could find.

[ Laughter ]

-I want to show a clip.

Here's Nick Jonas on "The Voice."

Take a look at this.

-You came out here and blew the three of us away.

Not John. -[ Laughs ]

I love Nick!

-You don't have to compete with me for this singer, so --

-But he's still taking you down. It's good.

-You're the kind of singer that I would die to write songs for.

And I'm -- -Ooh! Spitting that game.

[ Laughter ]

-Am I the kind of artist you can write songs for?

-I think I've submitted songs for you that you've turned down.

-What?! Have you? [ Audience ohs ]

-That's why I blocked you.

[ Laughter ]

-Okay, earned.

[ Cheers and applause ] -Yeah, come on.

It's gonna be great.

Say hi to everybody. -I will.

-I love everybody. Nick Jonas, everybody.
