Jack Antonoff, the indie-rocker beau of “Girls” creator Lena Dunham, had a sweetheart with even more star power during his high-school days: Scarlett Johansson.
The 30-year-old guitarist from the band Fun. had an unforgettable prom night in 2002 — as seen in these pics of him and the future sex symbol canoodling in a limo.
The couple dated for two years while attending the Professional Children’s School on the Upper West Side.
“When we were in high school, Jack was absolutely obsessed with her, and she broke his heart,” a prep-school pal told The Post. “They broke up shortly after graduation . . . She got swept up in the Hollywood scene.”
Dunham, 27, says she knows Antonoff’s romantic past and is not jealous.
