We have learned the simple truth, as Emerson said, that "The only way to have a friend is to be one."

Simon Cowell and I are great friends and we wind each other up. Rod Stewart and I do the same thing.

When I talk to kids, I'm really listening. When I do that, we have a little bit of a bigger connection than me being Kendrick Lamar and you being a student. It's almost like we're friends. Because a friend listens.

For me my friendship with Omar Rodriguez from Mars Volta that friendship really means a lot to me because he's another creative person who works as hard as I do.

A friend of mine, a friend of yours. My better half, Richard Stephen Sambora.

I'm gonna be your friend in high tide or in low tide.
