The 30-year-old actress recalled the scene from the 1994 Oscar-nominated adaptation of Anne Rice's novel during a recent photo shoot for a magazine, reported Los Angeles Times.
"It was just a peck. Everyone at the time was like, 'You're so lucky you kissed Brad Pitt,' but I thought it was disgusting. I didn't kiss anyone else until I was 16, I think. I was a late bloomer," Dunst said.
The 'Spider-Man' actress received a Golden Globe nomination for the film.
