On Nov. 25, while dining in a local restaurant with two pals, Vince befriended three female students at a nearby table — including Laura Mallory Lane, 20, a junior at Trinity University in San Antonio, Texas, who was on holiday while studying abroad in Rome. The group proceeded to have a cocktail-fueled evening that ended with Vaughn and Lane (who goes by her middle name of Mallory) in bed together — all of it documented in an e-mail entitled, "I shacked with Vince Vaughn" that Lane sent to 22 of her Gamma sorority sisters two days later, says a source! When the bars had closed at 2 a.m., Mallory wrote that the group ventured back to Vaughn's hotel and Vaughn asked her to stay for another drink — which she did. "I did not feel pressured at all," Mallory wrote. "We talked some more (and yes, we talked about Jen), and one thing led to another and obviously we were messing around before too long. We didn't have sex, but it was just as good :)"
No sex, huh? Well, whatever it is that they "had" was apparently enough to cause Jennifer to dump him. Here is a portion of the email that Vince's chick sent out to all of her sorority sisters:
See, if you're gonna cheat on your girlfriend, you prolly want to make sure that the chick you're cheating with isn't a blabber mouth. LOL! [Source, Source]
