Olympic skier Lindsey Vonn just confirmed on her Facebook page that she and Tiger Woods are indeed an item. In addition to being the best in their respective sports, Vonn and Woods have other things in common, too, such as knee surgery and recent divorces. Vonn, who was married to her coach, Thomas Vonn, for four years before divorcing last year, is recovering from season-ending knee surgery. (She reportedly flew home from Austria in a private jet provided by Woods after the injury last month, and spent the week before last aboard his yacht, "Privacy," recouping while he was winning at Doral.) "I guess it wasn't a well-kept secret but yes, I am dating Tiger Woods," she writes. "Our relationship evolved from a friendship into something more over these past few months and it has made me very happy." Most of the comments on her Facebook page were a little, er, catty, however. "Wish you luck," wrote one female follower, "but you can do soo much better." Meow!
