We got the lowdown on exercise, eating and what's considered a splurge.
StyleList: You're constantly jetting around the world. How do you keep from looking tired and jet-lagged?
Alessandra Ambrosio: Drinking a lot of water is great to stay hydrated. I don't like water, but I try to stay on it. When I get into a hotel I try to do 20 minutes of yoga to feel better after being all crunched up in the airplane. It opens your body a little bit and stretches you out.
Rosie Huntington-Whiteley: I know it's really boring, but I drink lots and lots of water -- it really works. I also love to use the moisturizers from Victoria's Secret. I love the apple flavor.
SL: What's your regular workout routine?
AA: I have a personal trainer who created the Brazilian Butt Lift class that mixes capoeira and samba. It's fun but you're still doing squats and getting exercise. I did cardio after I had my daughter to get in shape again, but I usually don't do cardio other than walking on the beach. I'm not a fan of going into the gym and running on a treadmill. I would rather go for a hike.
RHW: I go to the gym, do a lot of cardio and keep strong, which is really important to me.
SL: What food do you splurge on?
AA: I like to have a splurge wherever I am. I was in Milan the other day so for room service I had a pizza – a whole pizza. I think it's all about trying to be healthy, but to cheat a little bit sometimes. If you're in Milan, go have a pizza. If you're in Paris, go have a croissant. If you're here [in New York], have a cheeseburger. In Brazil, I have the Brazilian barbecue, but not every day. It's all balance."
RHW: I'm a huge eater --it can be anything from a roast dinner cooked by my mum, pizza or burgers. I love burgers and chips. I'm a British farm girl -- I love to eat -- it's really important part of my life.
