Michelle Trachtenberg

Known for playing devilish Georgina Sparks on "Gossip Girl," hottie Michelle Trachtenberg (who now has a starring role as a young nurse on NBC’s hit hospital drama "Mercy") brought to life some of our favorite sassy little girls. Think Penny from "Inspector Gadget" and Harriet, from Harriet the Spy.

Michelle was even nominated for a Daytime Emmy for "Truth or Scare," and we all know how little kids who are up for big awards turn out (looking at you Tatum O’Neil). Maybe Michelle’s mentor/friend/"Buffy" co-star Sarah Michelle Gellar helped keep her on the straight

and narrow, or maybe it was her other goody-goody classmates at Notre Dame Academy High School like Katharine McPhee and Rachel Bilson. Either way, we’re glad Michelle hasn’t left us for rehab yet and we’re hoping she stays around for a while.
