Lindsey Vonn and Tiger Woods spent time with each other's families

Although Lindsey Vonn and Tiger Woods have denied the rumors, things seem to be heating up between the Olympic skier and the pro golfer. So much, that they've even spent time with each other's families, according to Us Weekly.

Vonn's brother gave ski lessons to Woods' daughter Sam and son Charlie, reported the magazine.

This news comes after Woods gave gave Vonn a lift home on his private jet last week following her terrible skiing accident during the Alpine World Championships in Austria.

People magazine reports that the pair of athletes text and talk regularly.  More importantly, Woods' sordid past with women while he was married doesn't scare the blond beauty.

"She's not freaked out by his past, and that's what's really appealing to him," a source told People. "He really deserves to be happy.  He has been flogging himself for three years, and it's good to see him moving forward."

Vonn herself is recently divorced and insists her relationship with Woods is platonic.

"We are just friends," she told the Denver Post last month. "My brother was the ski instructor for his kids this November in Vail.  Guessing that's where [the initial report] came from."

Coincidence?  Hmmm.

"Tiger really does want a woman who he can have good conversations with," said the source. "He wants shared interests and outlooks.  He is finding that with [Lindsey]."

We've seen a little bit of the old Tiger back on the course recently. Maybe we're seeing it off of it as well.
