The former Baywatch star was seen sipping wine as she dined with a group of friends at the Boa restaurant in West Hollywood, but after raising her glass for a toast, the evening turned raunchy as the actress cavorted around one of her friends before straddling his lap.

In a video obtained by TMZ.com, Anderson can be seen brushing her fingers across her companion's lips before sitting on another man's lap and raising a leg in the air.

She then takes another of her fellow diners by the hand and pulls him to the middle of the restaurant where she performs an impromptu ballroom dance routine for amazed onlookers.
