Tiger Woods and Lindsey Vonn have not confirmed their relationship to the public, but according to Us Weekly, their actions speak much louder than their words and things are heating up between them.
The professional golfer and the Olympic skiier have been romantically linked since November 2012 when they were spotted skiing together in Austria. Months later, things still appear to be going well and the pair reportedly spent time with each other's families. The gossip magazine's latest issue, which hits newsstands Friday, reported that Vonn's brother provided ski lessons to Woods' daughter Sam, 5, and son Charlie, 4.
Woods, 37, share custody of the children with his ex-wife Elin Nordegren.
After Vonn hurt her knee in an accident during the Alpine Ski World Championships on Feb. 5, Woods had his private jet sent to Austria to fly the gold medal-winning skier home.
The couple's first meeting was at a charity event back in April 2012, but talk of romance did not occur until last fall.
"Their friendship slowly turned into a relationship," a source the magazine.
Vonn, 28, finalized her divorce from fellow skier Thomas Vonn in January and the source said she's not worried about moving ahead with her new beau, saying, "She is pretty carefree."
"Tiger and Lindsey have been friends for a while, and nothing started out romantically at all," a source told People magazine. "But they really have a lot in common and got close and closer. He still refers to her as 'my very good friend,' but he's been spending more and more time talking to her - and talking about her."
Last month, Vonn's reps kept quiet about the rumored relationship, telling People that her "focus is solely on competing and on defending her titles and thus she will not participate in any speculation surrounding her personal life at this time."
But the source close to both told People that both Woods and Vonn text and talk frequently.
