We were already mystified that anyone would want to date Tiger Woods ... but it turns out Lindsey Vonn is not only dating him, she's apparently quite happy about it. During a press conference yesterday about the Alpine skiing world championships, which start tomorrow, Vonn was asked when the golfer is arriving to watch her ski. "Oh, my god! I don't know, you should ask him," replied Vonn, whom the AP describes as giggling with a big grin on her face as she answered. "I have no idea. I have no idea."
