Shortly after filming had wrapped in 1994, Kirsten candidly said that she “hated” the kiss and found it “gross.” She told Entertainment Tonight, “I hated [the kiss] so much because Brad was like my older brother on set and it’s kind of like kissing your brother. It’s weird because he’s an older guy and I had to kiss him on the lips, so it was gross.”

A few years later, she once again noted that she was “so uncomfortable” while kissing Brad. “Kissing Brad was so uncomfortable for me. I remember saying in interviews that I thought it was gross, that Brad had cooties. I mean, I was 10,” she told Interview magazine.

More recently, in 2021, Kirsten said that kissing Brad was one of the “worst” things she had to do in the film. “I was a little girl and he was like a brother to me and it was very weird even though it was a peck. I was very not into it,” she said.
