Michelle Trachtenberg feels that she’s gotten her comeuppeance on her high school classmates through her movie success and her role as the evil Georgina Sparks on “Gossip Girl.” Trachtenberg told Complex magazine she was regularly taunted by other kids. “This one girl threw me down a flight of stairs, fractured my ribs, punched and fractured my nose, and told the principal I used the word ‘bitch’ and got me [sent to] detention — the only time I’ve ever been thrown in detention in my life.” The actress eventually got revenge on her nemesis later in life. “We were coming out of a restaurant and there was a wall of like 20 paparazzi,” she said. “They were probably waiting for Paris Hilton, and I just happened to come out. I have never before or since said something like this, because it’s so disgusting, but I turned to her and was like, ‘Oh, I’m sorry. I’m really famous. They need to take my picture. Sucks for you.’ “
