Nick Lachey NLACHEYGIRL020807_01.jpgJust who was the girl we spotted Nick Lachey with last night? After we spotted Nick leaving Sideways, we caught up with him at Teddy's with an unknown girl - and we do mean caught, as you can tell by our photos of the pair kissing in Nick's car and our video of them linking arms and walking into the club! But the topper? We stayed with him after he left Teddy's all the way to the Intercontinental Hotel - and saw him picking up Vanessa Minnillo!

We're guessing Jessica Simpson would flip her wig over this story - after all, it's only been a few days since she admitted to feeling "hurt" at seeing Nick hook up with Vanessa just a few weeks after their divorce!
