The actress and presenter reveals her love of ice cream and why getting eight hours sleep is essential.
Do you consider yourself to have a healthy lifestyle?
On the whole, I would consider myself to have a very healthy lifestyle. My approach to health is preventative. I've barely taken an antibiotic in 20 years.
I use acupuncture and homeopathy to keep everything in good order. I'm quite strict about what I eat. I do my shopping at the farmers market, get my five a day and exercise regularly.
But I'm no saint. Sometimes I just lose the will to make it to the gym and I'm well able to polish off a tub of Ben & Jerry's alone! A life without ice-cream is not one I'm prepared to live.
Do you exercise regularly? If so, what do you do?
I would get some kind of exercise in at least three times a week.
When I'm home in Dublin, I jog. The air is so much better here and there are green fields to run on. LA is smog laden. But the access to yoga and pilates there is fantastic so I do a lot of that. It's great for clearing the mind.
Do you do it willingly or begrudgingly?
I go through phases. Sometimes when I'm feeling really energised, I look forward to working out. If I'm going through a hectic time I find it really hard to fit it in.
It's always something I have to consciously factor in. I'm not one of those people that bounds out of bed at the crack of dawn and heads to the gym. But when I go, I always feel great for it.
What time do you go to bed?
During the week, around 11.30. If I'm out at an event, that will be a bit later If I'm shooting something or have an early appointment, I'll try to get to bed earlier. I'm an eight-hour-a-night gal.
What time do you get up in the morning?
On average, 8.30. If I'm working, I'll be up earlier. Sometimes I'll take an early yoga or pilates class, which would start at 8. At the weekend, I sleep in. I'm like a bear; I can sleep anywhere and for eons. A 12-hour sleep is not unusual for me.
What do you have for breakfast?
Every morning starts with a glass of fresh juice or a smoothie with two tablespoons of Udo's Oil. I've been doing that for years. My mom got me on to it and she has amazing skin so I didn't need any convincing.
If I'm doing some morning exercise, I'll leave it at that. Otherwise, I'll have a bowl of porridge with Greek yogurt, fruit and seeds after my juice.
I chuck all kinds of things into the juicer – kale, ginger, beetroot, parsley – whatever I can lay my hands on. Plus the usual suspects – oranges, apples, carrots.
Mostly I'll have a big salad. Often goats' cheese and pecans will find their way in there.
Bottled salad dressings are a pet hate of mine. Why bother when you can make something far nicer and healthier in two minutes yourself?
If I'm home at lunchtime, I'll lob a bit of Udo's in with apple cider vinegar, lemon juice or red wine vinegar. That's a new discovery for me. I've always had it in my morning juice but since working with them, I've discovered it's great in salad dressings too.
I have to have an iced coffee or cappuccino after lunch. That's my addiction. Oh and a square or two of dark chocolate. I prefer the taste of milk but I feel that dark isn't as naughty somehow.
I'd go out for dinner several times a week but I also love to cook. I throw big dinners at home in LA all the time.
I have loads of go-to recipes but I always like trying new things.
If it's an ordinary night and I'm exhausted and don't have much time, the quickest dinner for me is grilled fish, asparagus and steamed broccoli.
I grill the asparagus with olive oil and sprinkle sea salt on top. Broccoli tastes great with a little squeeze of fresh lemon juice.
If I've more time, I love roasting vegetables – butter nut squash and sweet potato especially.
But if I can't be bothered or the cupboards are empty, Thai town is a few minutes down the road so I'll pick up the phone for a delivery. That doesn't happen that often as I do make an effort to plan meals.
Porridge keeps me going till lunch. After lunch, I always have a few squares of black chocolate on the go. I love something sweet. I also got big into frozen yogurt when I moved over. Love that stuff.
Do you take any supplements?
I take Power Greens a few times a week. It's a great way to get a fix of greens to keep the blood at the right PH balance. I find it gives me great energy too.
How much water do you drink?
I go through fads of exercising lots or eating cleanly and then I fall off the wagon – skip classes and order the burger and fries instead of the fish and salad.
But one thing that remains close to constant is my water intake.
I rarely miss my 2.5-litre quota a day. I take water with me in the car, and always have a jug beside me if I'm working at the computer.
When I'm flying, I would easily neck a two-litre bottle and go looking for a refill.
Do you have a skincare routine?
Not really. I can see very quickly in my skin texture if I haven't been eating properly or getting enough water. No cream can replace that.
So my topical skincare routine is quite basic. I just bung on moisturiser on my face after the shower. My favourite is the original Creme De La Mer. It's expensive but it feels amazing – plus a little goes a long way.
One thing I'm religious about is SPF. I wear 50+ on my face, neck and the backs of my hands every day. Even in Ireland.
Food! Ice cream, chocolate, rich sauces, every kind of cheese, red wine, crunchy Italian bread ... I'm all about indulging in the things I love.
I haven't found the discipline to write high-calorie foods off the menu. Oh and wine. Can't forget that!
If I could change one thing about my lifestyle it would be ...
I'd like to worry less. I notice when I'm on track with exercise, that happens naturally. So I already know the answer to that one!
