Connolly's A Cheater!

Eric may have stayed with Sloan on Entourage, but Kevin Connolly can't say the same about his three-year, off-screen romance with Nicky Hilton. After learning that Kev cheated on her with Laguna Beach-native (and Kristin Cavallari BFF), Brittany Fields, Nicky dumped that chump, according to Perez Hilton. "Nicky is devastated," a source close to Hilton tells Perez. But it wasn't like Brittany was keeping her lips zipped about the affair, which apparently happened when Nicky was at Fashion Week in New York. "Brittany was so careless! She was bragging to everyone that she hooked up with Kevin last month," another source tells Perez. "The two met at an after-hours party in L.A., and well...you know the rest." We're officially on Team Nicky for this one!
