Nick Lachey and Vanessa Minnillo have taken their relationship to the next step by shacking up together. Earlier this week, the couple braved a spring storm to move into a two-bedroom condo in NYC's Atelier building. "Nick carried the huge boxes while Vanessa helped with the small ones," says a source. "They were soaked." Earlier reports suggested the pair were also bunking up in LA, although rep would not confirm the move. Last month, Minnillo told People mag that Lachey "is a nice guy. He's in the studio recording right now [in] LA, Nashville, New York. All over, with something for everyone to look out for."source
