Looks like Tiger Woods is finally getting a taste of his own bitter medicine! Tiger's pretty girlfriend Lindsey Vonn has reportedly been on him, reports the National Enquirer.

Lindsey, was seen engaging in a very public and very hot make out session with an older hunk in Miami on Aug. 16.

Backstage at a Justin Timberlake and Jay Z concert in Miami, Lindsey reportedly "threw herself into his arms and they started on a long session of deep kissing that went on for several minutes. 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."

Lindsey, who was in Miami for a "LVTakesMiami" promotion and photo session for sponsor Red Bull, later tweeted: "Wow that was amazing! Best concert I've ever been to!"
