If I have a problem, stuff's going through my head, I feel like using, I usually go and talk to my dad... I decided to get sober a lot younger than he did. He first tried to get sober when he was like 32, I believe.

I don't want to come off like the jealous brother who wasn't getting the attention, but it was like no one was really into me anyway. I wasn't really a priority.

For a while I was suicidal and I tried to kill myself. I think I should have died about four times.

I had my group of friends, you know, like my real group of friends, and then I had, like, party friends.

I didn't get at first put into a rehab facility; I got put in a adolescent psychiatric unit for my detox.

I'd read things, like people criticizing me. But no one likes to read stuff about that, and probably the main thing that was getting to me was me mum's illness.

There's people outside our house; you get followed by photographers; you can't go out and have a cup of coffee with a friend without someone coming up to you.

I'm totally grateful for the fans my family has and I have; they gave me a lot of support when I was in treatment. But it was just odd, you know? It's stressful. Just the whole fact of being someone in the public eye.

If I have a problem, stuff's going through my head, I feel like using, I usually go and talk to my dad... I decided to get sober a lot younger than he did. He first tried to get sober when he was like 32, I believe.

As long as I know my head's in the right place, my feet are on the ground, I think I'll be fine.

I took a bottle of pills. I'd been in Europe and I had a lot of absinthe and I was just drinking and drinking, trying to, you know, just shut my body down.

Well, all I can say is, it's a day-by-day program, and so I'm very worried about relapsing, but I don't know. I don't want to use. I don't want to go back to that place because nothing good came of it. It was super dark; it's not nice.

I've been drinking and using since I was 13.

I was hanging out with no one under 21. I thought that if I really wanted to fit in I had to... show them that I was in a way just as adult as they were, 'cause I could hold my own just as well as they could, if not better.

Kelly has a rather bad habit of interrupting.

It's been real weird. It wasn't how I expected my life to turn out. Especially, mainly pertaining to the show. It never crossed my mind that one day I'm gonna be big and famous and have my own TV show, you know?

Dad was just an emotional wreck. He was drinking a lot of the time, he was smoking a lot of pot. And because he takes certain medications, the drinking was making him... you know, he wasn't even present, really.

'Adapt and overcome' is my new motto.

I had about four days of like, 'Pity party, woe is me, it's all over.' Then I did some research and spoke with doctors and got in contact with people who have MS, and I soon realized it's actually a lot more manageable than the kind of public perception of it is, and that's part of the reason why I've been so outspoken about it.

I have a tendency to really stuff things. I don't really express, you know? Like, express certain feelings and stuff.

I'm the kind of person that, if someone says, 'Oh yeah, you can't do that,' I want to then go do it.

It never crossed my mind that one day I'm gonna be big and famous and have my own TV show, you know?

The strange thing is, no matter what, when you become some kind of public figure, you have your go-to answers for all scenarios and instances.

When I got diagnosed, the more research I did about it - MS overall, as a subject, as a disease - there's a lot of misconceptions and there's a lot of unknowns about it, and there wasn't anyone out that was close to my age or close to anything like me out there.

When my mum first told me she got sick, I didn't cry. I probably cried over my mum's illness twice.

You can't take good health for granted.

When we started making electronic music I imagined that the reaction we got from the rock musicians must have been similar to the one the beat groups got from people like my dad.

It was tough at the time but when I was younger, my Dad. I would say my Dad, because without him I wouldn't have been here. I mean it was tough for me because he was really demanding. With him, it was never enough, you know, anything I did was never enough.

David and Dad didn't get along too well growing up. I mean we all got along, but it was harder on David, because David wasn't going to be the son that Dad wanted. But now they're like best friends.

Where I come from, you don't really talk about how much you're earning. Those things are private. My dad never told my mum how much he was earning. I'm certainly not going to tell the world. I'm doing well.

I feel lazy when I'm not working. I learned all my business sense from my dad. He always believed in me, and I think the last thing he said to me before he passed away was, 'I know you're gonna be OK. I'm not worried about you'.

And I love Mel Brooks. My Dad loved his movies, too, they're awesome, the kind of thing that if you're in for ten minutes, you're in for two hours.

My mom and dad met at UCLA when he as a captain in the Air Force and she was in her junior year.

My dad was born in Chicago in 1908... his parents came from Russia. They settled in Chicago, where they lived in a little tiny grocery store with eight or nine children - in the backroom all together - and my grandmother got the idea to go into the movie business.

Mom and Dad would stay in bed on Sunday morning, but the kids would have to go to church.

My dad was dean of fine arts at the university. I was casting bronzes in the school foundry. I was using the university as a playground.

I have to remind my dad, 'Journalists - no matter how many cigars they smoke with you - are not your friends, so don't talk to them.'

We came from a family where we ran our own small business. Our dad made his own products. We made our own sausages, our own meatloafs, our own pickles. Dad had to do everything himself. He had to figure out how to finance his business.

My dad was a carpenter and I would work with him during the summer and umpire on the nights I wasn't playing.

It was sort of just a family sport. My mom and dad were pretty keen golfers when I was young and so were my grandparents, and I just sort of tagged along with them.

My dad takes care of me as a manager and as a dad. That's his job, you know, to take care of me. He has my best interests at heart.

My mom and dad are both in stand-up comedy, so that's where I started, that's where I got everything. My roots are holding the mic.

Joanna points her camera at a section of society unused to having cameras pointed at it. But I don't know about categorizing them in terms of class; I'm a bit wary of that. My dad is the son of a shipbuilder.

Now my dad is with me, traveling with me and a big part of this whole thing is I like to mix it up a little bit, you know. Who gets to take their father on a private jet across the country and stay in first class hotels? So we're enjoying it, but I'd stop if it's not possible.

It was my 16th birthday - my mom and dad gave me my Goya classical guitar that day. I sat down, wrote this song, and I just knew that that was the only thing I could ever really do - write songs and sing them to people.

Jenna's traveled with me; they've both traveled with their dad. This is the only time they've been old enough in all of their dad's campaigns to really be involved in.

I was a very sickly kid. While I was in the hospital at age 7, my Dad brought me a stack of comic books to keep me occupied. I was hooked.

My dad has no control over who works with me. Me, me and me alone has to take responsibility for anything.

My dad says I could sing before I could talk, if that's possible. I was always humming and things like that.
