In cities like Miami, my hair can get so frizzy, it looks crazy. I use TRESemm Extra Hold hairspray. I use a lot of it.

You'd be surprised at how many times I'd hit the ball, and the hair would go straight into my eyes. That's why, even when I play indoors, I wear a visor, because it stops that, and I'll apply a lot of gel and hairspray to keep it tight.

When we were kids, I remember we'd use lemon in our hair and go into the sun, hoping it would make us blond. Obviously, I have very dark hair and olive skin, and when I was a kid, I wanted to be blond, of course. It never worked.

As a people, Serbians are very tall, and we have olive skin and dark hair, which can look very nice. You have to be very beautiful to stand out.

I get massages almost daily. Sometimes I fall asleep during the massage, but it's very important to have deep-tissue massages because that type recovers muscles best.

It's not good to stretch when you're cold. Get your heart rate up, and once you finish, take time to stretch and let your body calm down.
