“Girls” star Lena Dunham took her maiden “Late Night” voyage Wednesday, and she immediately revealed why the appearance was so special. “I was really obsessed with you in high school in a way that was kind of crazy,” she gushed to Jimmy Fallon. “I don’t want to freak you out but I feel like there’s a lot of stuff I’ve wanted to say to you for a long time.” Fallon, at once flattered yet visibly uncomfortable by the admission thanked her and attempted to push the conversation in another direction. Undeterred, Dunham was a girl on a mission. She went on to describe a “Freaky Friday”-esque play she wrote about the two of them in high school in which they switched bodies and fell in love. Take a look at the two-part confessional above and below.
