"On my honor, I will try . . ." The Girl Scouts of America turns 100 today! While the girls' youth organization may best be known for its annual cookie sale — just this past weekend, Heidi Klum joined her daughter Leni, 7, in selling the tasty treats — it has spent the past century education and enriching the lives of more than 50 million young girls. Today, girls earn honors (or badges) for everything from fashion and makeup to the science of happiness. Check out which celeb tots have worked to earn their own Girl Scout badges over the years.
