What's Tiger Woods really like?
Vonn describes Woods as funny, laid back, competitive and a great guy. She also says they have similar personalities.
"He's goofy, like dorky," Vonn said. "He's probably not going to be that excited that I said that."
The "Katie" episode airs at 2 p.m. Tuesday on WESH-Channel 2.
Vonn, skater Evan Lysacek and hockey player Julie Chu tell Couric about preparations for the 2014 Winter Olympics. The program said that Lysacek debunks rumors that he was living with designer Vera Wang.
