Italian businessman Lapo Elkann thought he deserved a little extra something for dropping $196,000 at amfAR's 23rd Cinema Against AIDS Gala on Thursday night.
Uma Thurman hosted the event, where Lapo reportedly won the Victoria's Secret Fashion Show experience, a prize that included two tickets to next year's show and afterparty.
After laying down almost $200k for the auction, he was then photographed planting a wet one on Thurman's lips in the audience ... and wow, did he go for it.
While the "Pulp Fiction" star posed for photos with Lapo, we're told she was "very unhappy" with what happened.
"It is opportunism at its worst. She wasn't complicit in it," Uma's rep tells toofab. "Somewhere in his head he must have thought it an appropriate way of behaving. It clearly wasn't."
"She is very unhappy that this happened to her and feels violated," the statement adds.
The photos of the kiss were later removed from Getty at the actress' request.
