Tiger Woods and Lindsey Vonn may not be ready to talk about their relationship, but actions speak louder than words -- and their actions say things are heating up. The womanizing golfer and Olympic skier have been linked romantically ever since November, when they were spotted hitting the slopes together in Austria, and months later, it seems they're still going strong.
In fact, as reported in the new issue of Us Weekly, on stands Friday, the undercover twosome have even spent time with each other's families: Vonn's brother recently gave ski lessons to Woods' daughter Sam, 5, and son Charlie, 4. (The divorced golfer, 37, shares custody with ex-wife Elin Nordegren.)
Another sign of the hush-hush pair's devotion? After Vonn injured her knee in an accident during the super-G at the Alpine Ski World Championships on Feb. 5, Woods sent his private jet to Austria to fly the gold medal-winning skier home.
The couple first met at a charity event in April 2012, but things didn't get romantic until later that fall. "Their friendship slowly turned into a relationship," an insider tells Us.
Indeed, neither Woods nor Vonn appears to be in a rush to settle down again. Vonn, 28, finalized her divorce from fellow skier Thomas Vonn just last month, and a source says she's not worried about moving forward with her new beau. "She is pretty carefree," the source tells Us.
