Nick & Vanessa's Hot Date
07/25/2006 AT 11:50 AM EDT
Lachey, in jeans and a button-down shirt, and Minnillo, in a red dress, began the night chatting in their booth with Russell Simmons before Minnillo danced on the banquet to Shakira's "Hips Don't Lie" and "Gasolina."
When Jay-Z's "99 Problems" came on at around 12:45 a.m., Minnillo indulged Lachey in what would be the first of several lap dances.
Shortly thereafter, she was up on the banquet again, dancing with Jamie-Lynn Sigler to the Jackson 5's "Want You Back" and "Sweet Home Alabama."
When Justin Timberlake's "SexyBack" came on, Minnillo settled into Lachey's lap and sang it to him. But the song that Lachey enjoyed the most was the Rocky theme, "Eye of the Tiger," which got him waving his arms and moving his head to the beat.
Later, Lachey did shots with Wilmer Valderrama, who was holding court with friends including Erika Christensen.
Finally, Lachey and Minnillo left at 3 a.m., holding hands.
A rep for Lachey had no comment.
