Nick Lachey has fallen in love with Vanessa Minnillo - and he's talking about it on stage. "Damn it, Vegas, I fell in love again!" the singer said at a recent concert in Vegas. Following his split nearly a year ago from Jessica Simpson, Lachey began quietly dating the TRL host about seven months ago, and the couple recently celebrated their shared birthday. A source revealed that Minnillo commissioned a portrait of four generations of Lachey men for his birthday, saying, "It's based on one of Nick's favorite family pictures."source
