Jelena Jankovic opned up about her different personalities: Her fun-loving side off the court, and her more serious and driven side on the court.

“It’s like as soon as I step off the court I’m like really goofy and I just like to laugh and talk,” she told reporters in Charleston. “But when I step on the court it’s like I turn into a totally different person. It’s like I become the dragon that spits fire every time. I make a mistake and I’m like spitting fire, like yelling and doing all this. But it’s really like two personalities.”
