Lindsey Vonn Cheated on Tiger: Witness

Just try to read this and not feel a little bit gleeful: Lindsey Vonn has reportedly cheated on Tiger Woods. Of course, this report comes courtesy of the National Enquirer and must therefore be taken with a few grains of salt ... but still. "Lindsey is not a nun," as one source explains. Vonn was spotted backstage at last month's Justin Timberlake-Jay Z concert in Miami, making out with someone from JT's tour, according to Radar, which got a look at the article. (Just to remind you, the Enquirer did correctly break the story of Tiger's own cheating scandal.)

Lindsey appeared to know the guy very well, says a witness who proceeds to get extremely detailed: "She threw herself into his arms and they started on a long session of deep kissing that went on for several minutes. ... 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." The first source tells the Enquirer that Woods and Vonn will likely break up over this, which means no more gross interviews and awkwardly staged photos. (More Lindsey Vonn stories.)
