Nick Lachey Haunted By a Voice From the Past

Nick Lachey is a happy guy these days. He's got a better singing career than he ever had when he was married, and doesn't have to spend time with that half-wit Jessica Simpson either.

But that doesn't mean the memories from his unhappy union aren't lingering. Even as our boy Nick celebrates a joyous occasion - his birthday, as well as the birthday of his new squeeze, the sweet and vastly superior Vanessa Minnillo - he can't help but become enraged and suicidal when certain songs are played over the club's sound system.

Yes, Nick, we totally understand. Listening to Ashlee Simpson will drive your into a blinding rage. It certainly happens to us. We can't even imagine what it's like when she's your sister-in-law and you have to pretend she doesn't suck ass.
