Side dish

Kimora Lee Simmons went lip-to-lip with a gorgeous blond woman at Cipriani Upstairs Thursday.

The mystery kisser, who'd been hanging with Simmons at her table all evening, got up on the bar for a dirty dance as the 6-foot stunner shimmied in front of her. Blondie then gave Simmons an eyebrow-raising smooch. A rep for the Baby Phat designer, who was no doubt excited about her show at the tents the next day, says it was "a friendly kiss hello to a party guest."

No doubt the party picked up when Britney Spears showed up the next night.

Im going to say Gwen Stephani, all the "no doubt" hints.
