Pop crooner Nick Lachey proved he's over his ex-wife Jessica Simpson by taking new girlfriend Vanessa Minnillo home to meet his parents.

The What's Left of Me star whisked the MTV beauty back to his childhood home in Cincinnati, Ohio, to spend the Labor Day weekend with his friends and family.

A source says, "Nick likes to go home and spend Labor Day with his parents and brother, and he brought Vanessa. They're in a good place."

Minnillo gushes, "I feel very much at home being here with Nick's family in his hometown. I never meant to fall in love, but look how happy I am with Nick!"
