You can stay in situations just for the sake of it. That can be a very dangerous thing and tough on your soul and heart.

You need to be experimental. You try things, and it is OK if they don't always work necessarily.

Having the guts to be the person you are is what makes you brave.

As a kid, I was called Tintin because of my hair colour and style.

I did a bit of running away when my mam passed away. I didn't go back to work; I started drinking quite a lot, and I know how damaging that can be.

I'm not doing 'Once' to prove that I'm worldly or cultured. I just love the role.

The toughest challenges I've faced are the deaths of my mother and Stephen Gately.

I'd like less Irish-looking skin.

When greeting Pope Benedict a few years ago, I was meant to kiss the papal ring but I head-butted his hand instead. He just laughed at me.

I wouldn't want anyone to go through what my mam did - she was ill for two and a half years with breast cancer that moved to her spine, and died in 1998, when she was 51.

I've always been quite an insecure person.

I put up a front to make people think I had all of this confidence in myself, which I didn't.

I've always had to work to feel reassured, to feel secure, and that's not nice because you don't know where you stand.

I'm a good dad. I'm proud of that.

I grew up as the youngest child in a big, noisy family, and there was always someone around to hang out with.

As a working-class boy, golf was never really on my radar, and when I was growing up, Irish football was my sporting passion.

A musical is never something I thought I'd do.

It's that kind of Dublin mentality: you just have to grin and bear some things.

Being in a boy band, everyone has an opinion of all of us and what we do. There was a time I fought with that.

The industry has changed in that it is far more disposable than it used to be. When Boyzone came out, we were given a shot and the patience to record our singles and albums. Nowadays, the thought is if it is not working, then the artist will be dropped. The record companies will bail on the artists, and I find that sad.

We'll never do a show without honouring Steo in some shape or form, and that's really important to us.

I cook and do my own laundry.

People deserve to be happy.

I always wanted to make my parents feel proud of me.

Me and me dad didn't have a great relationship when we were younger. We had a good relationship, but it wasn't an affectionate relationship.

The most influential person in my life had been George Michael. He was very important to me and was one of my musical heroes growing up. Then he became a friend and mentor and someone I'd lean on.

Twenty-five years has been a good run. Boy bands like Boyzone don't get to last this long, usually.

Not a lot of bands get to go out on their own terms.

It was amazing to be on the map, to be recognised by other artists, and to be so successful.

The beauty of being in Boyzone - and maybe other bands are the same - is that as soon as you're back together again, it doesn't matter how long you've been apart. It feels like nothing's changed.

I have done a lot of interviews over the years, so you think I would know how to handle difficult questions, etc. But the truth is, I don't.

I do not regret the end of my first marriage.

I had spent so long trying to be the perfect husband.

I'm unbelievably ticklish. When I was a little kid, my sisters would hold me down and tickle me until I peed my pants.

I just want to tailgate, drink beer, and hang out in the middle of nowhere in a pick-up truck. That's my ideal date.

People say to me all the time, 'You have no fear.' I tell them, 'No, that's not true. I'm scared all the time. You have to have fear in order to have courage. I'm a courageous person because I'm a scared person.'

There are so many ridiculous arguments that MMA is somehow anti-woman.

I think it's hilarious if people say that my body looks masculine.

You go through every single inch of the emotional spectrum on fight week. You're the most stressed out you've ever been, you're the most pressured you've ever been, you're the happiest you've ever been - it's hard. It's exhausting.

I love waking up to Sunday morning pancakes. The whole process of making them, just out in the kitchen together making pancakes on a Sunday morning; that's an experience every girl should have.

I like quoting 'Lord of the Rings': 'My list of allies grows thin! My list of enemies grows long!'

I wear sunglasses almost all the time outside - not because I think I'm really, really cool, but because of the rays.

I don't feel the need to be the hot chick every second of the day. I like to be able to surprise people when I turn it on. I want it to be like the movie 'She's All That' when they unveil her.

That's the thing I'm worst at: resting. I have to be forced to do it. Sometimes I think of loopholes. 'Oh, I'm just going for a walk, up a dune that's 45 degrees, but I'm walking, so it's not a workout.'

There's no way to recover after tarnishing an undefeated record.

I'm the champion for a reason.

My first injury ever was a broken toe, and my mother made me run laps around the mat for the rest of the night. She said she wanted me to know that even if I was hurt, I was still fine.

If I can represent that body type of women that isn't represented so much in media, then I'd be happy to do that.

I have a candle permanently on my Jacuzzi because I love me some candles.

When I was in school, martial arts made you a dork, and I became self-conscious that I was too masculine. I was a 16-year-old girl with ringworm and cauliflower ears. People made fun of my arms and called me 'Miss Man.' It wasn't until I got older that I realized: These people are idiots. I'm fabulous.
