Tiger Woods and Lindsey Vonn are both professional athletes, so it's understandable that their relationship can be intense sometimes.
"We're really competitive with everything, ping pong, tennis and whatever," Vonn told USA Today. "I usually lose, which is really depressing."
Woods, 37, and Vonn, 28, announced that they were dating in March. Since then, they've gotten serious, and the professional skier has even spent time with the golfer's two children.
And though Woods may have the advantage when it comes to sports, there is one thing Vonn excels at.
"The hand-slapping game," she said with a laugh. "I've got better reflexes and better balance."
