“It's just impossible to believe I've become good friends with some stars like Justin Bieber. I would call Justin a friend, someone I hang out with. It's really weird.”

“If a man whistles at you, don't turn around. You are a lady not a dog.”

“Cause I'm Irish, and everyone remembers me.”

“I've not actually been on too many dates.”

“I've got an IQ of 40 million.”

“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'm the kind of boy that can fall in love with any girl because I love with the heart, not the eyes.”

“I'm an emotional guy, so I don't have to worry about a girl trying to get me to open up.”

“I don't want to live up to how people expect me to be.”

“I just like sitting at home, chilling and watching a movie.”

“Fans always tell me I'm beautiful, but no one will ever be as beautiful as them.”

“I think there's so much feeling among young girls where they feel like they have to be this perfect thing - and they don't. Perfect people don't exist. Sometimes people need to be told it.”

“I'd rather be a kid and play with paper planes, than be a man and play with a woman's heart.”

“Katy Perry is the sexiest woman I've ever kissed. It was amazing and very purple - she had purple lipstick on. I don't think there will ever be anything cooler than kissing her... until I marry her maybe!”

“I actually haven't been on many dates, but I like just chilling around at home and watching a movie with a girl.”

“I get really nervous if pigeons are flying around before shows. I can't stand them after one once flew in through my bathroom window and went for me while I was having a wee. That was enough. I think pigeons target me.”

“I had a girlfriend when I was about 13 but we didn't stay together for very long and I've not really been out with many people since. I've still never had a serious girlfriend but I would happily go out with someone if the right girl came along.”

“Someone told me the smile on my face gets bigger when I play the guitar.”

“I'm the most carefree, happy person you'll meet.”

“I was starstruck by Michelle Obama. She's an amazing-looking lady, and I'm a massive Barack Obama fan anyway.”
