The two were on hand tonight at PETA's 35th anniversary gala in Hollywood.
Anderson co-hosted the star-studded event with Anjelica Huston. Lee was among the honorees.
Photographers snapped pics of Anderson, who looked fab in a dark blue Vivienne Westwood gown, and the Mötley Crüe rocker together after they greeted each other with a kiss inside the ballroom of The Palladium.
But don't get any ideas that a romance has been reignited. Not only did Lee have his wife-to-be Sofia Toufa by his side, but he and Anderson didn't sit at the same table nor did he mention his former wife in his acceptance speech.
