Katy Perry still gets me every time. She's very funny in person! We met at the Teen Choice Awards and she pulled my cheeks apart and told me how cute I was. My life was literally flashing before my eyes!

I'd rather be called a boy and play with paper airplanes than be called a man and play with a girl's heart.

You'll never love yourself half as much as I love you and you'll never treat yourself right darling but I want ya too if I let you knoooowww Im here for you then maybe you'll love yourself like I love you ohhhhh

A personal highlight was probably when we got a No. 1 in the U.K. and when the album went to No. 1 in America. The top four that week was us, Adele, Guns N' Roses and Bruce Springsteen. It was ridiculous seeing those names there. Being the first band from the U.K. and Ireland to go to America and debut at No. 1 is just unbelievable.

I'd rather be a boy playing with a paper plane, than to be a grown man playing with a woman's heart.

I don't see how you could get used to people screaming in your face, and anyone who says different is lying.

The bigger the crowd the better really! The noise calms your nerves.
