Indie-rocker Jack Antonoff of the band fun. (and now Bleachers) may be dating "Girls" creator and star Lena Dunham now, but you'll never guess who he took to prom in 2002.

According to reports, it looks like Jack's high school sweetheart was Scarlett Johansson! Apparently, they dated for 2 years while both attending the Professional Children's School in New York City.

One of their school friends told the New York Post, "When we were in high school, Jack was absolutely obsessed with her, and she broke his heart. They broke up shortly after graduation ... She got swept up in the Hollywood scene."
