Nick Lachey and Vanessa Minnillo’s relationship seems to be getting more serious, with Nick staying at Vanessa’s home whenever he’s in New York.

A source close to Nick told People magazine: “Up until about a week ago, he was still pretty obsessed with [ex-wife Jessica Simpson]. He was devastated. But now he’s over it.”

“Vanessa hasn’t said she loves him yet but they get along really well and he stays with her when he is in town.”
