World champion skier and Tiger Woods' girlfriend Lindsey Vonn was reportedly caught romancing another man at a Justin Timberlake and Jay-Z concert last month, the Daily Mail reported on Wednesday.

Vonn, whose relationship with the world's most popular golfer was revealed earlier this year, was allegedly spotted having several minutes of 'deep kissing' with an older hunk backstage during the concert.

"After the concert was over, Lindsey and a group of female friends, carrying drinks, made their way backstage, and Lindsey spotted a guy she very obviously knew well," a source told the National Enquirer via Daily Mail. "She threw herself into his arms and they started on a long session of deep kissing that went on for several minutes."

The report sparked tremendous reactions around the sporting and entertainment world, as well on social media, given Tiger's history of infidelity with his ex-wife Elin Nordegren.

However, the 28-year-old Vonn vehemently denied the reports, calling it a made-up story.  

"There is not an ounce of truth in this clearly made up story," Vonn representative told the Daily Mail.

According to Larry Brown Sports, the report casts a doubt of uncertainty on the current status of relationship of the sporting couple.

"The last we heard from Lindsey regarding Tiger was when she called him the greatest of all time back on Aug. 4, so we have no way of confirming if the couple was still together as of Aug. 16. It should also be noted that Vonn has indeed expressed frustration with having to live in Tiger's shadow," Larry Brown writer Steve DelVecchio said in his article.

Vonn is scheduled to start skiing again later this year as she prepares for the upcoming Winter Olympics in Sochi, Russia. On the other hand, Woods is currently competing in the third leg of the FedEx Cup at the BMW Championship.
