Tiger Woods could be getting a taste of his own medicine. According to Radar Online, Lindsey Vonn was spotted kissing a mystery man backstage at a Justin Timberlake and Jay Z concert in Miami.

The 28-year-old was reportedly having some drinks with a friend backstage when she ran into a guy she knew, a source told The National Enquirer.

"She threw herself into his arms and they started on a long session of deep kissing that went on for several minutes," the source said. "He was a tall, good-looking man, in his mid-40s, with graying temples. They were really going at it. They were both holding drinks, and Lindsey's free hand was around his neck, drawing him closer, while his hand was gripping her rear end."

According to Radar, Vonn was in Miami for a "LVTakesMiami" promotion for Red Bull. The source said the pro athlete was just "checking out the playing field" and it probably wasn't anything serious. 

"Lindsey's not a nun," the source continued. "She's a very physical, very attractive young woman with a very strong athlete's ego. She wants her own fame - not his."

It was reported in the past that the Olympic skier was afraid Woods would cheat on her with his ex-wife Elin Nordegren. According to Fox Sports, Woods went on a family vacation with Nordegren and their two kids to Sweden and Vonn was worried sparks would fly between the two again. 

"Lindsey is convinced that Tiger still has feelings for Elin and, if he got the chance, he would dump Lindsey in a flash and get back together with her," Fox reports.

Nordegren famously split with Woods after finding out about his affairs with dozens of women. Following the scandal he met and began dating Vonn in 2012 after meeting her at a charity event. According to the New York Post, Vonn has nothing to worry about.

Woods' ex-wife reportedly gave her blessings to the couple and think they are good for each other.

"[Nordegren] really likes Lindsey and thinks she is a very good influence on Tiger," a source told the newspaper. [Tiger] seems happy with Lindsey, and she gets on well with their children."
