It’s Michelle Trachtenberg!
It’s hard to believe the Buffy and Gossip Girl actress is 27 years old -- she still looks like a teenager!
Michelle posted this school picture to Twitter with the caption, “Is it Summer vacation yet? #Kindergarden”
At this point, she was already working in commercials, but it wasn’t until 1994 that she landed her role in The Adventures of Pete & Pete as Nona Mecklenberg. Her real breakthrough role came in 1996, when she played the titular character in Harriet the Spy!
Did you guess who it was?
