Vanessa Minnillo

It looks like Nick Lachey and Vanessa Minnilo are back on, eh? At least we think that's them in the picture.

The undead couple threw a rocking bash this weekend to celebrate Halloween.

Other guests included Kara Dioguardi, Kate Beckinsale, Tommy Lee, and Wilmer Valderrama. So, not exactly A-list, but hey, it looks like they're having a good time.

Nick Lachey and Vanessa Minnillo have split.

The couple who have been dating for three years “have amicably split, but remain good friends who still greatly care for one another," Minnillo's rep confirmed.

They met on the set of Lachey’s music video for his song What’s Left of Me in 2006 after Vanessa had just ended her three-year relationship with New York Yankees all-star, Derek Jeter and Lachey had just gotten divorced from Jessica Simpson.

Who’s the molester-lookin’ dude lurking behind Vanessa Minnillo? Because it’s definitely not Nick Lachey, Vanessa’s boyfriend since 2006!

Minnillo was spotted with a new buggy eyed mystery man enjoying a night out in Manhattan last night. Are they just friends or is Nick being replaced by someone who looks like he’d eat your babies and has human heads stored in his freezer.

He’s so Norman Bates. Scary!
